Practical C Programming

How to do it…

1. Define an array of 10 elements:

#define max 10int stack[max];

2. Define two mutex objects—one to indicate the pop operation of the stack (pop_mutex), and another to represent the push operation of the stack (push_mutex):

pthread_mutex_t pop_mutex;pthread_mutex_t push_mutex;

3. To use the stack, the value of top is initialized to -1:

int top=-1;

4. Define two variables of the type pthread_t, to store two thread identifiers:

pthread_t tid1,tid2;

5. Invoke the pthread_create function to create the first thread. The thread is created with the default attributes, and the push function is executed to create the thread:

pthread_create(&tid1,NULL,&push,NULL);

6. Invoke the pthread_create function again to create the second thread. The thread ...
