PACKFILE_VTABLE(3)		Allegro	manual		    PACKFILE_VTABLE(3)

NAME
       PACKFILE_VTABLE	- Packfile vtable structure, for custom	packfiles. Al-
       legro 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.
