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.SEE ALSO
