multithreading - Mutex among threads of same process -


i using mutex prevent same process being executed twice, in way:

createmutex( null, true, "mutexname" ); if ( getlasterror() == error_already_exists ) { return 1;}

so if mutex exists in system, process exits.

now wandering, possible similar thing among threads of same process? give thread mutex, , exit if thread same mutex exists in process.
