Declaration [src]

GSocket*
g_socket_new_from_fd (
  gint fd,
  GError** error
)

Description [src]

Creates a new GSocket from a native file descriptor or winsock SOCKET handle.

This reads all the settings from the file descriptor so that all properties should work. Note that the file descriptor will be set to non-blocking mode, independent on the blocking mode of the GSocket.

On success, the returned GSocket takes ownership of fd. On failure, the caller must close fd themselves.

Since GLib 2.46, it is no longer a fatal error to call this on a non-socket descriptor. Instead, a GError will be set with code G_IO_ERROR_FAILED.

Available since: 2.22

Parameters

fd

Type: gint

A native socket file descriptor.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the constructor if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: GSocket

A GSocket or NULL on error. Free the returned object with g_object_unref().

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