g_socket_send_to (
  GSocket* socket,
  GSocketAddress* address,
  const gchar* buffer,
  gsize size,
  GCancellable* cancellable,
  GError** error
)

See g_socket_send() for additional information.

Available since: 2.22

Parameters

address

Type: GSocketAddress

A GSocketAddress, or NULL.

The argument can be NULL.

The data is owned by the caller of the method.

buffer

Type: An array of guint8

The buffer containing the data to send.

The length of the array is specified in the size argument.

The data is owned by the caller of the method.

size

Type: gsize

The number of bytes to send.

cancellable

Type: GCancellable

A %GCancellable or NULL.

The argument can be NULL.

The data is owned by the caller of the method.

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 method 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: gssize

Number of bytes written (which may be less than size), or -1 on error.
