Send "abort signal" to MEX

I'm playing around in Matlab with MEX-files, right now coding the mandelbrot set. Works well so far, except that with high zooms, the iterations have to go up and thus the execution takes a while. I'd like to send an "abort signal" to the MEX-code when I change settings in Matlab (for example new zoom factor), so that the MEX-code can immediatly start calculating the new settings. Is it possible to, for example, update a variable used in MEX (maybe a variable in workspace that a pointer in MEX points to)? Like a boolean "abort" that I can check in the iteration-loops in MEX?

You could check from inside the MEX function, is a key is pressed.
Or you can use mexCallMATLAB to run a drawnow command and request the status of a GUI object, e.g. a button. This takes some time, but it should be enough to trigger this every second.
