C CRITICAL_SECTION in windows2 min read

CRITICAL_SECTION (MSDN) in Windows can be used for thread synchronization. Essentially you can create a variable and limit it’s ownership to one thread at a time.  Something like this

Threads block while waiting for ownership of counter . So only one thread will have access to counter  at a time.

Earlier we have created a TCP server using winsock (https://jijnasu.in/c-tcp-server-in-windows-thread-per-connection/). Let’s make use of CRITICAL_SECTION to count the number of requests served by our server.
