Hello :}
I'm writing C-based console applications under Windows NT and am trying
to find a more useful way of debugging them.
Specifically, I would like to find out the exact string being sent from
the console application to the VISA dll. This would probably be similar
to something that NI-SPY does. However, since the console application
is assembling the string on the fly (and therefore a lot of times %s is
sent), NI-SPY isn't very useful.
What I would like to be able to do is something like this:
// Partial C example
void main()
{
ViSession vis;
char buffer[256] = "\0";
char String1[256]="\0", String2[256]="\0", SendString[256]="\0";
ViUInt32 Count = 0;
.
.
.
sprintf(SendS
tring, "%s%s", String1, String2); // combine the
strings to send
StartSpy(/*whatever parameters are needed here*/);
/* StartSpy would alert whatever (dll? includes?) to start
recording what's being
sent to VISA. */
viWrite(vis, SendString, 256, &Count);
EndSpy(buffer, /*whatever other parameters are needed.*/);
/* buffer would then contain whatever was sent to VISA via viWrite.
It should have the exact same contents as SendString... but this
is
needed for more complex debugging purposes elsewhere. */
.
.
.
}
Any idea, leads, points-in-the-right-direction?
Thanks!
Scott
