The SDK had a problem setting the socket to listen for incoming connections.
This error only happens during initialization (i.e. UpnpInit2).
#define UPNP_E_NETWORK_ERROR -200 |
A network error occurred.
It is the generic error code for network problems that are not covered under one of the more specific error codes. The typical meaning is the SDK failed to read the local IP address or had problems configuring one of the sockets.

This occurs in any function that makes network connections, such as discovery (e.g. UpnpSearchAsync or UpnpSendAdvertisement), control (e.g. UpnpSendAction), eventing (e.g. UpnpNotify), and HTTP functions (e.g. UpnpDownloadXmlDoc).
#define UPNP_E_SUBSCRIBE_UNACCEPTED -301 |
A subscription request was rejected from the remote side.
#define UPNP_E_SUCCESS 0 |
The operation completed successfully.
For asynchronous functions, this only means that the packet generated by the operation was successfully transmitted on the network. The result of the entire operation comes as part of the callback for that operation.
#define UPNP_E_TIMEDOUT -207 |
Too much time elapsed before the required number of bytes were sent or received over a socket.

This function must be called before any other API function can be called. It should be called only once. Subsequent calls to this API return a UPNP_E_INIT
error code.
Optionally, the application can specify an interface name (in the case of a multi-homed configuration) and a port number to use for all UPnP operations. Since a port number can be used only by one process, multiple processes using the SDK must specify different port numbers.
If unspecified, the SDK will use the first suitable interface and an arbitrary port.

The description can also be configured to have the correct IP and port address.
NOTE: For the configuration to be functional, the internal web server MUST be present. In addition, the web server MUST be activated (using UpnpSetWebServerRootDir) before calling this function. The only condition where the web server can be absent is if the description document is specified as a URL and no configuration is required (i.e. config_baseURL = 0
.)
This is a synchronous call and does not generate any callbacks. Callbacks can occur as soon as this function returns.
Examples of using different types of description documents:
1) Description specified as a URL: descriptionType == UPNPREG_URL_DESC description is the URL bufferLen = 0 (ignored) 2) Description specified as a file: descriptionType == UPNPREG_FILENAME_DESC description is a filename bufferLen = 0 (ignored) 3) Description specified as a memory buffer: descriptionType == UPNPREG_BUF_DESC description is pointer to a memory buffer bufferLen == length of memory buffer

Searches for devices matching the given search target.
The function returns immediately and the SDK calls the default callback function, registered during the UpnpRegisterClient call, for each matching root device, device, or service. The application specifies the search type by the Target parameter.
This function searches for the devices for the provided maximum time. It is an asynchronous function. It schedules a search job and returns. The client is notified about the search results after search timer.
Note that there is no way for the SDK to distinguish which client instance issued a particular search. Therefore, the client can get search callbacks that do not match the original criteria of the search. Also, the application will receive multiple callbacks for each search.

Global variable to determine the maximum number of seconds which an event can spend on a subscription queue (waiting for the event at the head of the queue to be communicated). This parameter will have no effect in most situations with the default (low) value of MAX_SUBSCRIPTION_QUEUED_EVENTS. However, if MAX_SUBSCRIPTION_QUEUED_EVENTS is set to a high value, the AGE parameter will allow pruning the queue in good conformance with the UPnP Device Architecture standard, at the price of higher potential memory use.
