MathLink C Function


int MLPutMessage(MLINK link, int msg)
sends the message msg to the link object link.
  • MathLink messages provide out-of-band message sending and receiving that is not tied to the normal transfer of data.
  • MLPutMessage() returns 0 in the event of an error, and a nonzero value if the function succeeds.
  • Use MLError() to retrieve the error code if MLPutMessage() fails.
  • MLPutMessage() is declared in the MathLink header file mathlink.h.
#include "mathlink.h"

/* send an abort message to a link */

void f(MLINK lp)
    if(! MLPutMessage(lp, MLAbortMessage))
        { /* unable to send message to lp */ }
