wait and notify in C/C++ shared memory

Question

How to wait and notify like in Java In C/C++ for shared memory between two or more thread?I use pthread library.

Answer 1

Using Condition Variables is one way to do it: those are available when using the pthread library under Linux (see link).

A condition variable is a variable of type pthread_cond_t and is used with the appropriate functions for waiting and later, process continuation.
