/* 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.
*/
void vsf_secbuf_alloc(char** p_ptr, unsigned int size);
/* vsf_secbuf_free()
* PURPOSE
* Frees a "secure buffer".
* PARAMETERS
* p_ptr - pointer to a pointer containing the buffer to be freed. The
* buffer pointer is nullified by this call.
