NAME

       load_datafile_object - Loads a specific object from a datafile. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       DATAFILE *load_datafile_object(const char *filename, const char *objectname);

DESCRIPTION

       Loads a specific object from a datafile. This won't work if you strip the object names from the file, and
       it will be very slow if you save the file with global compression. Example:

          /* Load only the music from the datafile. */
          music_object = load_datafile_object("datafile.dat",
                                              "MUSIC");
          /* Play it and wait a moment for it. */
          play_midi(music_object->dat);
          ...
          /* Destroy unneeded music. */
          unload_datafile_object(music_object);

RETURN VALUE

       Returns a pointer to a single DATAFILE element whose `dat' member points to the object, or NULL if  there
       was  an  error  or  there  was no object with the requested name. Remember to free this DATAFILE later to
       avoid memory leaks, but use the correct unloading function!
