Return value
Long. Returns the result of the sendmsg. This formula will populate a COPYDATASTRUCT and send a WM_COPYDATA message (message number 74) to the window pointed to by handle. The wparam argument can be any long value but is typically the handle of the calling program. The longdata argument will be copied into the dwdata parameter of the COPYDATASTRUCT. The stringdata will be pointed to by the lpdata parameter of a COPYDATASTRUCT. This function will wait for a return from the sendmsg.
