Function Documentation

int cg_upnp_av_control_invokeaction (  CgUpnpService *  upnpService, char *  actionName, char **  errorString,   ... )

Invoke an action on the upnp device Parameters: upnpDevice  The UPnP device actionName  The name of the action to invoke errorString  A newly-created error string if the action fails. Pass NULL if you don't want to use it. numArgs  The number of action-specific arguments ...  A list of action-specific arguments Returns: An integer containing the UPnP status code The list of action-specific arguments is a comma-separated list, that is organised as pairs of char* ARG_NAME and CgString* ARG_VALUE. ARG_NAME contains the name of the argument, while ARG_VALUE contains the value of the argument. You don't need to put anything inside OUT arguments, as they are not sent along with the action; their contents are set when the action post returns with OUT values that were received from the peer.

BOOL cg_upnp_av_control_iserrorcodesuccessful (  int  errorCode  )

Check, whether a UPnP error/status code is actually a success. Parameters: errorCode  The error/status code Returns: TRUE if the code is not an error; otherwise FALSE

int cg_upnp_av_control_parseactionarguments (  CgUpnpAction *  action, BOOL  inDirection, va_list *  va )

A helper function to set or get dynamic action arguments to/from an action. Parameters: action  The UPnP action inDirection  Use TRUE for IN arguments, FALSE for OUT arguments va  The dynamic argument list, followed by a single NULL Returns: upnp error code
