** This function is NOT part of the sqlite3 public API. It is strictly

|
|
**
|
|
** ACHTUNG: it was discovered on 2023-08-11 that, with SQLITE_DEBUG,
|
|
** this function's out-of-scope use of the sqlite3_vfs/file/io_methods
|
|
** APIs leads to triggering of assertions in the core library. Its use
|
|
** is now deprecated and VFS-specific APIs for importing files need to
|
|
** be found to replace it. sqlite3_wasm_posix_create_file() is
|
|
** suitable for the "unix" family of VFSes.
|
|
**
|
|
** Creates a new file using the I/O API of the given VFS, containing
|
|
** the given number of bytes of the given data. If the file exists, it
|
|
** is truncated to the given length and populated with the given
|
|
** data.
|
|
**
|
|
** This function exists so that we can implement the equivalent of
|
|
** Emscripten's FS.createDataFile() in a VFS-agnostic way. This
|
|
** functionality is intended for use in uploading database files.
|
|
**
|
|
** Not all VFSes support this functionality, e.g. the "kvvfs" does
|
|
** not.
|
|
**
|
|
** If pVfs is NULL, sqlite3_vfs_find(0) is used.
|
|
**
|
|
** If zFile is NULL, pVfs is NULL (and sqlite3_vfs_find(0) returns
|
|
** NULL), or nData is negative, SQLITE_MISUSE are returned.
|
|
**
|
|
** On success, it creates a new file with the given name, populated
|
|
** with the fist nData bytes of pData. If pData is NULL, the file is
|
|
** created and/or truncated to nData bytes.
|
|
**
|
|
** Whether or not directory components of zFilename are created
|
|
** automatically or not is unspecified: that detail is left to the
|
|
** VFS. The "opfs" VFS, for example, creates them.
|
|
**
|
|
** If an error happens while populating or truncating the file, the
|
|
** target file will be deleted (if needed) if this function created
|
|
** it. If this function did not create it, it is not deleted but may
|
|
** be left in an undefined state.
|
|
**
|
|
** Returns 0 on success. On error, it returns a code described above
|
|
** or propagates a code from one of the I/O methods.
|
|
**
|
|
** Design note: nData is an integer, instead of int64, for WASM
|
|
** portability, so that the API can still work in builds where BigInt
|
|
** support is disabled or unavailable.
