Function fluidlite_sys::fluid_is_soundfont

pub unsafe extern "C" fn fluid_is_soundfont(filename: *mut c_char) -> c_int

fluid_is_soundfont returns 1 if the specified filename is a soundfont. It retuns 0 otherwise. The current implementation only checks for the "RIFF" header in the file. It is useful only to distinguish between SoundFonts and MIDI files.
