C#. How to pass message from unsafe callback to managed code?
- by maxima120
Is there a simple example of how to pass messages from unsafe callback to managed code?
I have a proprietary dll which receives some messages packed in structs and all is coming to a callback function.
The example of usage is as follows but it calls unsafe code too. I want to pass the messages into my application which is all managed code.
*P.S. I have no experience in interop or unsafe code. I used to develop in C++ 8 yrs ago but remember very little from that nightmarish times :)
P.P.S. The application is loaded as hell, the original devs claim it processes 2mil messages per sec.. I need a most efficient solution.*
static unsafe int OnCoreCallback(IntPtr pSys, IntPtr pMsg)
{
// Alias structure pointers to the pointers passed in.
CoreSystem* pCoreSys = (CoreSystem*)pSys;
CoreMessage* pCoreMsg = (CoreMessage*)pMsg;
// message handler function.
if (pCoreMsg->MessageType == Core.MSG_STATUS)
OnCoreStatus(pCoreSys, pCoreMsg);
// Continue running
return (int)Core.CALLBACKRETURN_CONTINUE;
}
Thank you.
