LIBRARY LINK SYMBOL
processMathLink
calls Mathematica to process the expression written onto a link.
DetailsDetails
- Used in C/C++ code in a library function called from Mathematica.
- Typically, the expression written on the link will contain EvaluatePacket; the result will be a ReturnPacket.
- A zero error code value will be returned if there is an error.

The following gets a MathLink connection and uses it to send a message to the kernel:
int success;
MLINK link = libData->getMathLink(libData);
MLPutFunction( link, "EvaluatePacket", 1);
MLPutFunction( link, "Message", 2);
MLPutFunction( link, "MessageName", 2);
MLPutSymbol( link, "MyFunction");
MLPutString( link, "info");
MLPutString( link, "Message called from within DLL function.");
success = libData->processMathLink( link);
if (!success) return success;
pkt = MLNextPacket( link);
if ( pkt == RETURNPKT) {
MLNewPacket(link);
}
