pack_fopen_vtable(3)            Allegro manual            pack_fopen_vtable(3)



NAME
       pack_fopen_vtable - Allegro game programming library.

SYNOPSIS
       #include <allegro.h>


       PACKFILE *pack_fopen_vtable(const PACKFILE_VTABLE *vtable, void
       *userdata);

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().

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'.
