       #include <allegro.h>

       SAMPLE *load_sample(const char *filename);

DESCRIPTION

       Loads  a  sample from a file, supporting both mono and stereo WAV and mono VOC files, in 8 or 16-bit formats, as well as formats handled by
       functions registered using register_sample_file_type(). Example:

	  SAMPLE *sample = load_sample(user_input);
	  if (!sample)
	     abort_on_error("Couldn't load sample!");

RETURN VALUE

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