How do I get the Handle of an Existing Task?

[bsimon]

I'm using a National Instruments board with Matlab.  This is allowing me to perform interactive command-line development.  But, I've run into an interesting problem.  I can create a task and forget the handle.  Now I cannot use the task (forgot the handle), but it is still allocated and I cannot re-use the task name (until I stop & restart Matlab).  I realize this is sloppy programming and simply a result of me typing in DAQ commands one at a time from a command line, but - is there any way to return a task handle if the task name is known?  I've searched for a function int32 __CFUNC DAQmxGetTask(const char taskName[], TaskHandle *taskHandle) but it doesn't seem to exist.  Any chance you guys could write one and add it to the library?  It would make interactive development through Matlab easier.

Hello bsimon,

It's been a while since I've programmed in Matlab and I've never used DAQmx in Matlab (in my experience, LabVIEW, CVI, C/C++, any of the .NET languages and even VB, though I hate it, would seem to be vastly superior ADEs because the DAQmx API actually supports these languages).  In spite of my stated inexperience, if you are just making C function calls from the command-line, can't you just 1) directly access whatever variable you are currently passing in for *taskHandle OR 2) explicitly create a TaskHandle *taskHandle at the command line and just access this variable?

I can & will keep track of the memory objects - but life would be easier if you could determine if a task exists by name, and then get the handle without secondary ops (such as setting the handle to NULL after a DAQmxClearTask and later testing for handle = NULL before attempting a another create).

As much as possible I'd like to create stateless routines.  Local storage and setting the handle to NULL after a clear would do the trick, I was just hoping for a NIDAQmx call to return the handle.
