I have an OS/2 (V1.3) program in which I am attempting to use DosExitList()
to invoke a function to perform certain cleanup operations primarily
involving flushing an array to disk and closing the associated file.
I am having some difficulty with this because the program will hang
(instead of exiting) when Ctrl-C terminates the program. The system has to be
restarted to recover.

It appears that my exit routine is not even being called since debug
printf(s) never print when this situation occurs. The program will run to
completion normally if Ctrl-C is not hit, and the exit handler is entered
and functions normally.

Any insight?
