al_make_temp_file - Allegro 5 API

       Make a temporary randomly named file given a filename `template'.

       `template' is a string giving the format of the generated filename and should include one or more capital
       Xs.   The  Xs  are  replaced  with  random alphanumeric characters, produced using a simple pseudo-random
       number generator only.  There should be no path separators.

       If `ret_path' is not NULL, the address it points to will be set to point to a new path structure with the
       name of the temporary file.

       Returns the opened ALLEGRO_FILE(3alleg5) on success, NULL on failure.
