intmain() { Semaphoresem(0);//Let one current or future thread throughsem.Post();//Wait until the semaphore is posted (incremented)sem.WaitAndDecrement(); } Child Processes This class makes it easy to spawn child processes and to capture the output they send to stdout and stderr. ...
Access to the shared memory is synchronized using a semaphore. The primary thread (main) creates a semaphore object and uses this object to handshake with the secondary thread (thread_function). The primary thread instantiates the semaphore in a state that prevents the secondary thread from ...
