pthreads defines a set of C programming language types, functions and constants. It is implemented with a pthread.h header and a thread library.. There are around 100 threads procedures, all prefixed pthread_ and they can be categorized into five groups:
Reentrancy is a programming concept where a function or subroutine can be interrupted and then resumed before it finishes executing. This means that the function can be called again before it completes its previous execution.
The functions pthread_key_create and pthread_key_delete are used respectively to create and delete a key for thread-specific data. The type of the key is explicitly left opaque and is referred to as pthread_key_t. This key can be seen by all threads. In each thread, the key can be associated with thread-specific data via pthread_setspecific.
