293 The function @code{close_range} closes the file descriptor from @var{lowfd}
318 The @var{lowfd} value is larger than @var{maxfd} or an unsupported @var{flags}
337 @deftypefun void closefrom (int @var{lowfd})
342 to @var{lowfd}. This function is similar to calling
343 @code{close} for all open file descriptors not less than @var{lowfd}.
