Function mupdf_sys::fz_archive_format

pub unsafe extern "C" fn fz_archive_format(
    ctx: *mut fz_context, 
    arch: *mut fz_archive
) -> *const c_char

Return a pointer to a string describing the format of the archive.

The lifetime of the string is unspecified (in current implementations the string will persist until the archive is closed, but this is not guaranteed).
