load_datafile (3) Linux Manual Page

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.
