Function mupdf_sys::fz_new_document_writer_with_output

pub unsafe extern "C" fn fz_new_document_writer_with_output(
    ctx: *mut fz_context, 
    out: *mut fz_output, 
    format: *const c_char, 
    options: *const c_char
) -> *mut fz_document_writer

Like fz_new_document_writer but takes a fz_output for writing the result. Only works for multi-page formats.
