The code and the flow looks fine but when we see the output : $. The above code is a simple one in which two threads(jobs) are created and in the start function of these threads, a counter is maintained through which user gets the logs about job number which is started and when it is completed. Printf("\ncan't create thread :", strerror(err)) Lets take an example code to study synchronization problems : #includeĮrr = pthread_create(&(tid), NULL, &doSomeThing, NULL) Linux Threads Series: part 1, part 2, part 3, part 4 (this article). In this article we will throw some light on an important aspect known as thread synchronization.

The Open Group Base Specifications Issue 7, IEEE Std 1003.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.

State Threads, an event driven approach to threading.

Beginthread (a subroutine within Windows for creating a new thread and unix thread).

Grand Central Dispatch (Apple's thread library).

not mapped on Win32/Win64 API but built directly on the operating system syscall interface.

Interix environment subsystem available in the Windows Services for UNIX/Subsystem for UNIX-based Applications package provides a native port of the pthreads API, i.e. The Mingw-w64 project also contains a wrapper implementation of pthreads, winpthreads, which tries to use more native system calls than the Pthreads4w project. Version 2.11.0, released under the LGPLv3 license, is also 64-bit or 32-bit compatible.

Pthreads4w version 3.0.0 or later, released under the Apache Public License v2.0, is compatible with 64-bit or 32-bit Windows systems.

It can also be used to port Unix software (which uses pthreads) with little or no modification to the Windows platform.

Windows does not support the pthreads standard natively, therefore the Pthreads4w project seeks to provide a portable and open-source wrapper implementation. THREAD 3: Will be sleeping for 4 seconds. THREAD 4: Will be sleeping for 1 seconds. THREAD 2: Will be sleeping for 4 seconds. THREAD 1: Will be sleeping for 5 seconds. THREAD 0: Will be sleeping for 3 seconds. Here is one of the many possible outputs from running this program. Gcc pthreads_demo.c -pthread -o pthreads_demo This program can be compiled using the gcc compiler with the following command: If a programmer wanted the threads to communicate with each other, this would require defining a variable outside of the scope of any of the functions, making it a global variable.

This program creates five threads, each executing the function perform_work that prints the unique number of this thread to standard output. #include #include #include #include #include #define NUM_THREADS 5 void * perform_work ( void * arguments )
