al_identify_bitmap_f(1) Allegro 5 API

SYNOPSIS


#include <allegro5/allegro.h>
char const *al_identify_bitmap_f(ALLEGRO_FILE *fp)

DESCRIPTION

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.

Returns a pointer to a static string with a file extension for the type, including the leading dot. For example ".png" or ".jpg". Returns NULL if the bitmap type cannot be determined.
