#include Creating a Thread ( pthread_create ) pthread_create is the function of pthread.h header file, which is used to create a thread. It requires a mutex of the associated shared resource value it is waiting on. Then, how to compile C program with pthread.h library? They are in libpthrea, therefore, we should add -lpthread to link our program. In the Linux threads series, we discussed on the ways in which a thread can terminate and how the return status is passed on from the terminating thread to its parent thread. The syntax and parameters details are given as follows: POSIX Threads, or Pthreads provides API which are available on many Unix-like POSIX systems such as FreeBSD, NetBSD, GNU/Linux, Mac OS X and Solaris. Linux implementations of POSIX threads Over time, two threading implementations have been provided by the GNU C library on Linux: LinuxThreads This is the original Pthreads implementation. The command is: gcc thread.c -o thread -lpthread. The following routine is used to create a POSIX thread − As Example 4-12 shows, the producer thread acquires the mutex protecting the buffer data structure and then makes certain that space is available for the item being produced. The following routine is used to create a POSIX thread − This tutorial assumes that you are working on Linux OS and we are going to write multi-threaded C program using POSIX. This tutorial assumes that you are working on Linux OS and we are going to write multi-threaded C++ program using POSIX. To compile C program with pthread.h library, you have to put -lpthread just after the compile command gcc thread.c -o thread, this command will tell to the compiler to execute program with pthread.h library.. pthread_cond_wait() puts the current thread to sleep. Pthreads are defined as a set of C language programming types and procedure calls, implemented with a pthread.h header file. DESCRIPTION top The pthread_detach() function marks the thread identified by thread as detached. This could be useful if you want to loop the threads, for example. PTHREAD_DETACH(3) Linux Programmer's Manual PTHREAD_DETACH(3) NAME top pthread_detach - detach a thread SYNOPSIS top #include int pthread_detach(pthread_t thread); Compile and link with -pthread. pthread_cond_broadcast() signals all threads waiting on the cond condition variable to wakeup. In GNU/Linux, the pthread functions are not included in the standard C library. status contains a pointer to the status argument passed by the ending thread as part of pthread_exit(). pthread_cond_signal() signals one thread out of the possibly many sleeping threads to wakeup. POSIX Threads, or Pthreads provides API which are available on many Unix-like POSIX systems such as FreeBSD, NetBSD, GNU/Linux, Mac OS X and Solaris. gcc is the compiler command. A pthreads Tutorial 8 June 2016 31 March 2015 by Faye Williams I’m going to use a simple program to illustrate the basic use of pthreads, and highlight some of the issues that you may run into when you’re creating your own threaded programs (for C++11 threads, see this post ). An example of using pthread's condition variables, showing how to block a main thread while waiting for worker threads to finish their work, without joining the threads. Compiling on Linux On Linux, programs that use the Pthreads API should be compiled using cc -pthread. It is returned by pthread_create() and used by the application in function calls that require a thread identifier. - cond.c Creating Threads. Thread ID is represented by type pthread_t. pthread_t is the data type used to uniquely identify a thread. The pthread_tryjoin_np() function performs a nonblocking join with the thread thread, returning the exit status of the thread in *retval.
