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'.
