// The xFileControl() method is a generic interface that allows custom

// is incremented. The iVersion value started out as 1 in
// SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2

// to 3 with SQLite [version 3.7.6] on [dateof:3.7.6]. Additional fields
// may be appended to the sqlite3_vfs object and the iVersion value
// may increase again in future versions of SQLite.
// Note that due to an oversight, the structure
// of the sqlite3_vfs object changed in the transition from
// SQLite [version 3.5.9] to [version 3.6.0] on [dateof:3.6.0]
// and yet the iVersion field was not increased.
//
// The szOsFile field is the size of the subclassed [sqlite3_file]
// structure used by this VFS. mxPathname is the maximum length of
// a pathname in this VFS.
//
// Registered sqlite3_vfs objects are kept on a linked list formed by
// the pNext pointer. The [sqlite3_vfs_register()]
// and [sqlite3_vfs_unregister()] interfaces manage this list
// in a thread-safe way. The [sqlite3_vfs_find()] interface
// searches the list. Neither the application code nor the VFS
// implementation should use the pNext pointer.
//
// The pNext field is the only field in the sqlite3_vfs
// structure that SQLite will ever modify. SQLite will only access
// or modify this field while holding a particular static mutex.
// The application should never modify anything within the sqlite3_vfs
// object once the object has been registered.
//
// The zName field holds the name of the VFS module. The name must
// be unique across all VFS modules.
//
// [[sqlite3_vfs.xOpen]]
// ^SQLite guarantees that the zFilename parameter to xOpen
// is either a NULL pointer or string obtained
// from xFullPathname() with an optional suffix added.
// ^If a suffix is added to the zFilename parameter, it will
// consist of a single "-" character followed by no more than
// 11 alphanumeric and/or "-" characters.
// ^SQLite further guarantees that
// the string will be valid and unchanged until xClose() is
// called. Because of the previous sentence,
// the [sqlite3_file] can safely store a pointer to the
// filename if it needs to remember the filename for some reason.
// If the zFilename parameter to xOpen is a NULL pointer then xOpen
// must invent its own temporary name for the file. ^Whenever the
// xFilename parameter is NULL it will also be the case that the
// flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
//
// The flags argument to xOpen() includes all bits set in
// the flags argument to [sqlite3_open_v2()]. Or if [sqlite3_open()]
// or [sqlite3_open16()] is used, then flags includes at least
// [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE].
// If xOpen() opens a file read-only then it sets *pOutFlags to
// include [SQLITE_OPEN_READONLY]. Other bits in *pOutFlags may be set.
//
// ^(SQLite will also add one of the following flags to the xOpen()
// call, depending on the object being opened:
//
// <ul>
// <li> [SQLITE_OPEN_MAIN_DB]
// <li> [SQLITE_OPEN_MAIN_JOURNAL]
// <li> [SQLITE_OPEN_TEMP_DB]
// <li> [SQLITE_OPEN_TEMP_JOURNAL]

// <li> [SQLITE_OPEN_SUBJOURNAL]
// <li> [SQLITE_OPEN_SUPER_JOURNAL]
// <li> [SQLITE_OPEN_WAL]
// </ul>)^
//
// The file I/O implementation can use the object type flags to
// change the way it deals with files. For example, an application
// that does not care about crash recovery or rollback might make
// the open of a journal file a no-op. Writes to this journal would
// also be no-ops, and any attempt to read the journal would return
// SQLITE_IOERR. Or the implementation might recognize that a database
// file will be doing page-aligned sector reads and writes in a random
// order and set up its I/O subsystem accordingly.
//
// SQLite might also add one of the following flags to the xOpen method:
//
// <ul>
// <li> [SQLITE_OPEN_DELETEONCLOSE]
// <li> [SQLITE_OPEN_EXCLUSIVE]
// </ul>
//
// The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
// deleted when it is closed. ^The [SQLITE_OPEN_DELETEONCLOSE]
// will be set for TEMP databases and their journals, transient
// databases, and subjournals.
//
// ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
// with the [SQLITE_OPEN_CREATE] flag, which are both directly
// analogous to the O_EXCL and O_CREAT flags of the POSIX open()
// API. The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
// SQLITE_OPEN_CREATE, is used to indicate that file should always
// be created, and that it is an error if it already exists.
// It is <i>not</i> used to indicate the file should be opened
// for exclusive access.
//
// ^At least szOsFile bytes of memory are allocated by SQLite
// to hold the [sqlite3_file] structure passed as the third
// argument to xOpen. The xOpen method does not have to
// allocate the structure; it should just fill it in. Note that
// the xOpen method must set the sqlite3_file.pMethods to either
// a valid [sqlite3_io_methods] object or to NULL. xOpen must do
// this even if the open fails. SQLite expects that the sqlite3_file.pMethods
// element will be valid after xOpen returns regardless of the success
// or failure of the xOpen call.
//
// [[sqlite3_vfs.xAccess]]
// ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
// to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
// test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
// to test whether a file is at least readable. The SQLITE_ACCESS_READ
// flag is never actually used and is not implemented in the built-in
// VFSes of SQLite. The file is named by the second argument and can be a
// directory. The xAccess method returns [SQLITE_OK] on success or some
// non-zero error code if there is an I/O error or if the name of
// the file given in the second argument is illegal. If SQLITE_OK
// is returned, then non-zero or zero is written into *pResOut to indicate
// whether or not the file is accessible.
//
// ^SQLite will always allocate at least mxPathname+1 bytes for the
// output buffer xFullPathname. The exact size of the output buffer
// is also passed as a parameter to both methods. If the output buffer
// is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
// handled as a fatal error by SQLite, vfs implementations should endeavor
// to prevent this by setting mxPathname to a sufficiently large value.
//
// The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
// interfaces are not strictly a part of the filesystem, but they are
// included in the VFS structure for completeness.
// The xRandomness() function attempts to return nBytes bytes
// of good-quality randomness into zOut. The return value is
// the actual number of bytes of randomness obtained.
// The xSleep() method causes the calling thread to sleep for at
// least the number of microseconds given. ^The xCurrentTime()
// method returns a Julian Day Number for the current date and time as
// a floating point value.
// ^The xCurrentTimeInt64() method returns, as an integer, the Julian
// Day Number multiplied by 86400000 (the number of milliseconds in
// a 24-hour day).
// ^SQLite will use the xCurrentTimeInt64() method to get the current
// date and time if that method is available (if iVersion is 2 or
// greater and the function pointer is not NULL) and will fall back
// to xCurrentTime() if xCurrentTimeInt64() is unavailable.
//
// ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
// are not used by the SQLite core. These optional interfaces are provided
// by some VFSes to facilitate testing of the VFS code. By overriding
// system calls with functions under its control, a test program can
// simulate faults and error conditions that would otherwise be difficult
// or impossible to induce. The set of system calls that can be overridden
// varies from one VFS to another, and from one version of the same VFS to the
// next. Applications that use these interfaces must be prepared for any
// or all of these interfaces to be NULL or for their behavior to change
// from one release to the next. Applications must not attempt to access
// any of these methods if the iVersion of the VFS is less than 3.

// and yet the iVersion field was not increased.
//
// The szOsFile field is the size of the subclassed [sqlite3_file]
// structure used by this VFS. mxPathname is the maximum length of
// a pathname in this VFS.
//
// Registered sqlite3_vfs objects are kept on a linked list formed by
// the pNext pointer. The [sqlite3_vfs_register()]
// and [sqlite3_vfs_unregister()] interfaces manage this list
// in a thread-safe way. The [sqlite3_vfs_find()] interface
// searches the list. Neither the application code nor the VFS
// implementation should use the pNext pointer.
//
// The pNext field is the only field in the sqlite3_vfs
// structure that SQLite will ever modify. SQLite will only access
// or modify this field while holding a particular static mutex.
// The application should never modify anything within the sqlite3_vfs
// object once the object has been registered.
//
// The zName field holds the name of the VFS module. The name must
// be unique across all VFS modules.
//
// [[sqlite3_vfs.xOpen]]
// ^SQLite guarantees that the zFilename parameter to xOpen
// is either a NULL pointer or string obtained
// from xFullPathname() with an optional suffix added.
// ^If a suffix is added to the zFilename parameter, it will
// consist of a single "-" character followed by no more than
// 11 alphanumeric and/or "-" characters.
// ^SQLite further guarantees that
// the string will be valid and unchanged until xClose() is
// called. Because of the previous sentence,
// the [sqlite3_file] can safely store a pointer to the
// filename if it needs to remember the filename for some reason.
// If the zFilename parameter to xOpen is a NULL pointer then xOpen
// must invent its own temporary name for the file. ^Whenever the
// xFilename parameter is NULL it will also be the case that the
// flags parameter will include [SQLITE_OPEN_DELETEONCLOSE].
//
// The flags argument to xOpen() includes all bits set in
// the flags argument to [sqlite3_open_v2()]. Or if [sqlite3_open()]
// or [sqlite3_open16()] is used, then flags includes at least
// [SQLITE_OPEN_READWRITE] | [SQLITE_OPEN_CREATE].
// If xOpen() opens a file read-only then it sets *pOutFlags to
// include [SQLITE_OPEN_READONLY]. Other bits in *pOutFlags may be set.
//
// ^(SQLite will also add one of the following flags to the xOpen()
// call, depending on the object being opened:
//
// <ul>
// <li> [SQLITE_OPEN_MAIN_DB]
// <li> [SQLITE_OPEN_MAIN_JOURNAL]
// <li> [SQLITE_OPEN_TEMP_DB]
// <li> [SQLITE_OPEN_TEMP_JOURNAL]
// <li> [SQLITE_OPEN_TRANSIENT_DB]
// <li> [SQLITE_OPEN_SUBJOURNAL]
// <li> [SQLITE_OPEN_SUPER_JOURNAL]
// <li> [SQLITE_OPEN_WAL]
// </ul>)^
//
// The file I/O implementation can use the object type flags to
// change the way it deals with files. For example, an application
// that does not care about crash recovery or rollback might make
// the open of a journal file a no-op. Writes to this journal would
// also be no-ops, and any attempt to read the journal would return
// SQLITE_IOERR. Or the implementation might recognize that a database
// file will be doing page-aligned sector reads and writes in a random
// order and set up its I/O subsystem accordingly.
//
// SQLite might also add one of the following flags to the xOpen method:
//
// <ul>
// <li> [SQLITE_OPEN_DELETEONCLOSE]
// <li> [SQLITE_OPEN_EXCLUSIVE]
// </ul>
//
// The [SQLITE_OPEN_DELETEONCLOSE] flag means the file should be
// deleted when it is closed. ^The [SQLITE_OPEN_DELETEONCLOSE]
// will be set for TEMP databases and their journals, transient
// databases, and subjournals.
//
// ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
// with the [SQLITE_OPEN_CREATE] flag, which are both directly
// analogous to the O_EXCL and O_CREAT flags of the POSIX open()
// API. The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
// SQLITE_OPEN_CREATE, is used to indicate that file should always
// be created, and that it is an error if it already exists.
// It is <i>not</i> used to indicate the file should be opened
// for exclusive access.
//
// ^At least szOsFile bytes of memory are allocated by SQLite
// to hold the [sqlite3_file] structure passed as the third
// argument to xOpen. The xOpen method does not have to
// allocate the structure; it should just fill it in. Note that
// the xOpen method must set the sqlite3_file.pMethods to either
// a valid [sqlite3_io_methods] object or to NULL. xOpen must do
// this even if the open fails. SQLite expects that the sqlite3_file.pMethods
// element will be valid after xOpen returns regardless of the success
// or failure of the xOpen call.
//
// [[sqlite3_vfs.xAccess]]
// ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS]
// to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to
// test whether a file is readable and writable, or [SQLITE_ACCESS_READ]
// to test whether a file is at least readable. The SQLITE_ACCESS_READ
// flag is never actually used and is not implemented in the built-in
// VFSes of SQLite. The file is named by the second argument and can be a
// directory. The xAccess method returns [SQLITE_OK] on success or some
// non-zero error code if there is an I/O error or if the name of
// the file given in the second argument is illegal. If SQLITE_OK
// is returned, then non-zero or zero is written into *pResOut to indicate
// whether or not the file is accessible.
//
// ^SQLite will always allocate at least mxPathname+1 bytes for the
// output buffer xFullPathname. The exact size of the output buffer
// is also passed as a parameter to both methods. If the output buffer
// is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is
// handled as a fatal error by SQLite, vfs implementations should endeavor
// to prevent this by setting mxPathname to a sufficiently large value.
//
// The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64()
// interfaces are not strictly a part of the filesystem, but they are
// included in the VFS structure for completeness.
// The xRandomness() function attempts to return nBytes bytes
// of good-quality randomness into zOut. The return value is
// the actual number of bytes of randomness obtained.
// The xSleep() method causes the calling thread to sleep for at
// least the number of microseconds given. ^The xCurrentTime()
// method returns a Julian Day Number for the current date and time as
// a floating point value.
// ^The xCurrentTimeInt64() method returns, as an integer, the Julian
// Day Number multiplied by 86400000 (the number of milliseconds in
// a 24-hour day).
// ^SQLite will use the xCurrentTimeInt64() method to get the current
// date and time if that method is available (if iVersion is 2 or
// greater and the function pointer is not NULL) and will fall back
// to xCurrentTime() if xCurrentTimeInt64() is unavailable.
//
// ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces
// are not used by the SQLite core. These optional interfaces are provided
// by some VFSes to facilitate testing of the VFS code. By overriding
// system calls with functions under its control, a test program can
// simulate faults and error conditions that would otherwise be difficult
// or impossible to induce. The set of system calls that can be overridden
// varies from one VFS to another, and from one version of the same VFS to the
// next. Applications that use these interfaces must be prepared for any
// or all of these interfaces to be NULL or for their behavior to change
// from one release to the next. Applications must not attempt to access
// any of these methods if the iVersion of the VFS is less than 3.

// The colUsed field indicates which columns of the virtual table may be

//
// The xBestIndex method may optionally populate the idxFlags field with a

// SQLITE_INDEX_SCAN_UNIQUE. If the xBestIndex method sets this flag, SQLite
// assumes that the strategy may visit at most one row.
//
// Additionally, if xBestIndex sets the SQLITE_INDEX_SCAN_UNIQUE flag, then
// SQLite also assumes that if a call to the xUpdate() method is made as
// part of the same statement to delete or update a virtual table row and the
// implementation returns SQLITE_CONSTRAINT, then there is no need to rollback
// any database changes. In other words, if the xUpdate() returns
// SQLITE_CONSTRAINT, the database contents must be exactly as they were
// before xUpdate was called. By contrast, if SQLITE_INDEX_SCAN_UNIQUE is not
// set and xUpdate returns SQLITE_CONSTRAINT, any database changes made by
// the xUpdate method are automatically rolled back by SQLite.
//
// IMPORTANT: The estimatedRows field was added to the sqlite3_index_info

// If a virtual table extension is

// The <limits.h> files in some gcc versions don't define LLONG_MIN,
