GLib.IOChannel.unix_new
Description: Reference for GLib.IOChannel.unix_new

### Function

# GLib IOChannelunix_new

#### Declaration

    GIOChannel*
    g_io_channel_unix_new (
      int fd
    )

#### Description

Creates a new `GIOChannel` given a file descriptor. On UNIX systems this works for plain files, pipes, and sockets.

The returned `GIOChannel` has a reference count of 1.

The default encoding for `GIOChannel` is UTF-8. If your application is reading output from a command using via pipe, you may need to set the encoding to the encoding of the current locale (see g_get_charset()) with the `g_io_channel_set_encoding()` function. By default, the fd passed will not be closed when the final reference to the `GIOChannel` data structure is dropped.

If you want to read raw binary data without interpretation, then call the `g_io_channel_set_encoding()` function with `NULL` for the encoding argument.

This function is available in GLib on Windows, too, but you should avoid using it on Windows. The domain of file descriptors and sockets overlap. There is no way for GLib to know which one you mean in case the argument you pass to this function happens to be both a valid file descriptor and socket. If that happens a warning is issued, and GLib assumes that it is the file descriptor you mean.

#### Parameters

`fd`

  Type: `int`

  A file descriptor.

#### Return value

Type: `GIOChannel`

A new `GIOChannel`.

The caller of the function takes ownership of the data, and is responsible for freeing it.
