Type Alias __io_write_fn 

pub type __io_write_fn = Option<unsafe extern "C" fn(__cookie: *mut c_void, __buf: *const c_char, __n: usize) -> __ssize_t>;

Write N bytes pointed to by BUF to COOKIE. Write all N bytes unless there is an error. Return number of bytes written. If there is an error, return 0 and do not write anything. If the file has been opened for append (__mode.__append set), then set the file pointer to the end of the file and then do the write; if not, just write at the current file pointer.
