Help with Semaphore implementation
 

Hello ,
I am a newbee and I want to implement a semaphore which will do the

following :
4 threads want to do a printf .
Thread A ----> print A
Thread B -----> print B
Thread C ----> print C
thread C-----> print D
and the output must be ABCD.
How to do this on a Borlad TC 3.0 running on a windows machine?
Thank You
Sonu

1. Borland TC 3.0 does not support threads or memory sharing.

2. If you must do this with TC 3.0 use a "lock" file as a sempahore-like object.

3. TC 3.0 is a DOS compiler. DOS does not handle threads or context switching at all. It supports TSR's. I have no idea how you would run four processes and have them all execute in the same timespace. 4 TSR's?
How would you schedule the TSR's?

There are LOTS of free compilers - google for "C compiler download"
Unless you are locked into an old 286 machine that can't do Windows.

Hi ,
