Hello All!

a stupid question:
I don't want 2 copies of my program to run at the same time.
I use DosCreateMutEx to create a semaphore when starting the program, and
DosDeleteMutEx when I'm done. or do I ?. Should I use DosCreateMuxWaitSem
instead ?
My question is:
what is a good way to put so to speak copy 2 on hold until copy 1 is done ?
I have to check periodically for the semaphore, else just wait. When the
semaphore is gone, then I can safely resume. Is there a way to do this
without consuming any resources ? the doc talks about threads for the
muxwait, which is why I am not sure I can use it between 2 apps.
