Service

This handler is invoked by the service thread when an event occurs. For example, an interrupt service calls this routine from its interrupt thread. In the case of a polled service this handler is invoked from a thread which is waiting on a kernel alarm event. A port service handler is invoked from a thread performing a call to ReceiveRtMessage.

The handler is invoked with different parameters depending on the configuration. For the interrupt service and the polled service it is invoked as follows:

void Service(LPSERVICEDESC 
    pServiceDesc
);

For a port service it is invoked with the following parameters:

void Service(LPSERVICEDESC 

    pServiceDesc, 

    LPVOID pData, 

    LPRECEIVEINFO pInfo

);

Parameters

pServiceDesc

A pointer to the service descriptor.

pData

A pointer to a data buffer where the data part of the message was received.

pInfo

A pointer to a RECEIVEINFO structure describing the message just received.

In the case of a "custom" service type, it is up to the implementer what parameters are passed from the service thread to the service routine.
