NAME
PACKFILE_VTABLE - Packfile vtable structure, for custom packfiles. Allegro game programming library.
SYNOPSIS
#include <allegro.h> typedef struct PACKFILE_VTABLE
DESCRIPTION
int pf_fclose(void *userdata); int pf_getc(void *userdata); int pf_ungetc(int c, void *userdata); long pf_fread(void *p, long n, void *userdata); int pf_putc(int c, void *userdata); long pf_fwrite(const void *p, long n, void *userdata); int pf_fseek(void *userdata, int offset); int pf_feof(void *userdata); int pf_ferror(void *userdata); This is the vtable which must be provided for custom packfiles, which then can read from and write to wherever you like (eg. files in mem- ory). You should provide all the entries of the vtable, even if they are empty stubs doing nothing, to avoid Allegro (or you) calling a NULL method at some point.
