/* vsf_secbuf_alloc()
|
|
* PURPOSE
|
|
* Allocate a "secure buffer". A secure buffer is one which will attempt to
|
|
* catch out of bounds accesses by crashing the program (rather than
|
|
* corrupting memory). It works by using UNIX memory protection. It isn't
|
|
* foolproof.
|
|
* PARAMETERS
|
|
* p_ptr - pointer to a pointer which is to contain the secure buffer.
|
|
* Any previous buffer pointed to is freed.
|
|
* size - size in bytes required for the secure buffer.
