Line 614 The stream pointer is set at the end of the file.

Line 618 The stream pointer is set at the end of the file.

If successful, it returns a non-negative integer as the file descriptor.

Otherwise the system error function is called.

Unnecessary files should be closed by @code{close_file()}.

If the special file name unix://stdin or unix://stdout or unix://stderr

is given, it returns the file descriptor for the standard input or

the standard output or the standard error stream respectively.

The mode argument is ignored in this case.

@item @code{get_line()} reads a line from an opened file and returns the

line as a string. If no argument is supplied, it reads a line from the

standard input.
