.SH NAME
pack_fopen_vtable \- Allegro game programming library.\&
.SH SYNOPSIS
.B #include <allegro.h>

.sp
.B PACKFILE *pack_fopen_vtable(const PACKFILE_VTABLE *vtable, void *userdata);
.SH DESCRIPTION
Creates a new packfile structure that uses the functions specified in
the vtable instead of the standard functions. The data pointer by `vtable'
and `userdata' must remain available for the lifetime of the created
packfile.

While the created packfile structure can be used with other Allegro
functions, there are two limitations. First, opening chunks using
pack_fopen_chunk() on top of the returned packfile is not possible at this
time. And packfile_password() does not have any effect on packfiles opened
with pack_fopen_vtable().
.SH "RETURN VALUE"
On success, it returns a pointer to a PACKFILE structure, and on error it
returns NULL and stores an error code in `errno'.
