<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 <a class="el" href="classGlib_1_1IOChannel.html#a1a22bd01752d233c23babdef800c0d87" title="Create an I/O channel for C runtime (emulated Unix-like) file descriptors.

">create_from_win32_socket()</a> 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>
