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.

#Linking pthread c license

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.

#Linking pthread c software

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

#Linking pthread c portable

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 )
