NAME

load_datafile - Loads a datafile into memory. Allegro game programming library.  

SYNOPSIS

#include <allegro.h>

DATAFILE *load_datafile(const char *filename);  

DESCRIPTION

Loads a datafile into memory in one go. If the datafile has been encrypted, you must first call packfile_password() to set the appropriate key. If the datafile contains truecolor graphics, you must set the video mode or call set_color_conversion() before loading it. Example: 

   /* Load the resources for our game. */
   DATAFILE *dat = load_datafile("game.dat");
   if (!dat)
      abort_on_error("Couldn't load sound resources!");
   /* Use resources. */
   ...
   /* Destroy them when we don't need them any more. */
   unload_datafile(dat);
 

RETURN VALUE

Returns a pointer to the DATAFILE, or NULL on error. Remember to free this DATAFILE later to avoid memory leaks.
