This example shows how to obtain information about all devices and services. It starts an infinite loop (use CLI), and if any of available devices or services are found, the proper callback function will be invoked.
Beispiel #1 Search for all UPnP devices and services.
<?php
/* Callback for available device */
function device_proxy_available_cb($proxy, $arg)
{
$info = gupnp_device_info_get($proxy);
$type = $info['device_type'];
$location = $info['location'];
printf("Device available:\n");
printf("\ttype: %s\n", $type);
printf("\tlocation: %s\n", $location);
}
/* Callback for available service */
function service_proxy_available_cb($proxy, $arg)
{
$info = gupnp_service_info_get($proxy);
$type = $info['service_type'];
$location = $info['location'];
printf("Service available:\n");
printf("\ttype: %s\n", $type);
printf("\tlocation: %s\n", $location);
}
/* Create the UPnP context */
$context = gupnp_context_new();
if (!$context) {
printf("Error creating the GUPnP context\n");
exit(-1);
}
/* We're interested in everything */
$cp = gupnp_control_point_new($context, "ssdp:all");
/* Set callbacks */
gupnp_control_point_callback_set($cp,
GUPNP_SIGNAL_DEVICE_PROXY_AVAILABLE, 'device_proxy_available_cb');
gupnp_control_point_callback_set($cp,
GUPNP_SIGNAL_SERVICE_PROXY_AVAILABLE, 'service_proxy_available_cb');
/* Start for browsing (infinite loop, hit Ctrl-C to interrupt) */
gupnp_control_point_browse_start($cp);
?>
