Call a waitbar from within a DLL written in C

Example code for embedding a call to the Matlab waitbar() function from within a DLL written in C

Description

When a DLL takes a long time to run, things go silent. It can look like the program has crashed even when it is running along just fine. The Matlab waitbar() function can be used in Matlab, but a waitbar is not available in C. However, Matlab can be called from C, so the user can still be notified that processing is still taking place. This code is an example of how to call the waitbar() from within a DLL that is written in C.

• MATLAB release: MATLAB 7.0.1 (R14SP1)

I don't understand how to use it...

Bill, you rock! I've been trying to figure out how to do this for an hour. In your example function, should the 'Processing...' string not be in double quotes, i.e., "Processing..." ?

To implement this, just copy Bill's 3 functions plus the declarations into your C mex file, and use Bill's functions in a loop within your mexFunction(), with the syntax as indicated in his example.
