<p>Note that IOChannels implement an automatic implicit character set conversion to the data stream, and usually will not pass by default binary data unchanged. To set the encoding of the channel, use e.g. set_encoding("ISO-8859-15"). To set the channel to no encoding, use <a class="el" href="classGlib_1_1IOChannel.html#ab1d3ae667bd425ef830929a67cf526e0" title="Sets the encoding for the input/output of the channel.

<p>Creates an I/O channel from a file descriptor. </p>
<p>On Unix, IOChannels created with this function work for any file descriptor or socket.</p>
<p>On Win32, this can be used either for files opened with the MSVCRT (the Microsoft run-time C library) <code>_open()</code> or <code>_pipe()</code>, including file descriptors 0, 1 and 2 (corresponding to <code>stdin</code>, <code>stdout</code> and <code>stderr</code>), or for Winsock <code>SOCKET</code>s. If the parameter is a legal file descriptor, it is assumed to be such, otherwise it should be a <code>SOCKET</code>. This relies on <code>SOCKET</code>s and file descriptors not overlapping. If you want to be certain, call either create_from_win32_fd() or create_from_win32_socket() instead as appropriate.</p>
<p>The term file descriptor as used in the context of Win32 refers to the emulated Unix-like file descriptors MSVCRT provides. The native corresponding concept is file <code>HANDLE</code>. There isn't as of yet a way to get IOChannels for Win32 file <code>HANDLE</code>s. </p>
