Also update gio/tests/send-data.c to test async connection, and free more stuff in several tests to make leaks easier to see.

* @error: a pointer to a #GError, or %NULL
|
|
*
|
|
* This is a helper function for g_socket_client_connect().
|
|
*
|
|
* Attempts to create a TCP connection to the named host.
|
|
*
|
|
* @host_and_port may be in any of a number of recognised formats: an IPv6
|
|
* address, an IPv4 address, or a domain name (in which case a DNS
|
|
* lookup is performed). Quoting with [] is supported for all address
|
|
* types. A port override may be specified in the usual way with a
|
|
* colon. Ports may be given as decimal numbers or symbolic names (in
|
|
* which case an /etc/services lookup is performed).
|
|
*
|
|
* If no port override is given in @host_and_port then @default_port will be
|
|
* used as the port number to connect to.
|
|
*
|
|
* In general, @host_and_port is expected to be provided by the user (allowing
|
|
* them to give the hostname, and a port overide if necessary) and
|
|
* @default_port is expected to be provided by the application.
|
|
*
|
|
* In the case that an IP address is given, a single connection
|
|
* attempt is made. In the case that a name is given, multiple
|
|
* connection attempts may be made, in turn and according to the
|
|
* number of address records in DNS, until a connection succeeds.
|
|
*
|
|
* Upon a successful connection, a new #GSocketConnection is constructed
|
|
* and returned. The caller owns this new object and must drop their
|
|
* reference to it when finished with it.
|
|
*
|
|
* In the event of any failure (DNS error, service not found, no hosts
|
|
* connectable) %NULL is returned and @error (if non-%NULL) is set
|
|
* accordingly.
|
|
*
|
|
Returns: a #GSocketConnection on success, %NULL on error.
