char const *al_identify_bitmap_f(ALLEGRO_FILE *fp)

.SH DESCRIPTION
.PP
Tries to guess the bitmap file type of the open ALLEGRO_FILE by reading
the first few bytes.
By default Allegro cannot recognize any file types, but calling
al_init_image_addon(3alleg5) will add detection of (some of) the types
it can read.
You can also use al_register_bitmap_identifier(3alleg5) to add
identification for custom file types.
.PP
Returns a pointer to a static string with a file extension for the type,
including the leading dot.
For example \[lq].png\[rq] or \[lq].jpg\[rq].
Returns NULL if the bitmap type cannot be determined.
