| | POSIX - encyclopedia article about POSIX. |
 | | POSIX is the collective name of a family of related standards specified by the IEEE to define the application program interface (API) for software designed to run on variants of the Unix OS. | | | POSIX specifies the user and software interfaces to the OS in some 15 different documents. | | | Since the IEEE charges very high rates for POSIX documentation and does not allow on-line publication of the standards, there has been a tendency toward the "Single UNIX Specification" standard, which is open, accepts input from anyone, and is freely available on the Internet. |

| | Windows NT Workstation Resource Kit: POSIX Compatibility |
| | POSIX is not limited to the UNIX environment, however. | | | POSIX, which stands for Portable Operating System Interface for computing environments, began as an effort by the IEEE community to promote the portability of applications across UNIX environments by developing a clear, consistent, and unambiguous set of standards. | | | POSIX requires a certain amount of functionality from the file system, such as the ability for a file to have more than one name (or hard links) and case-sensitive file naming. |

| | POSIX threads explained |
| | Think of it this way: if you write a program and don't use POSIX threads at all, the program will be single-threaded (this single thread is called the "main" thread). | | | This lack of genealogy has one major implication: if you want to wait for a thread to terminate, you need to specify which one you are waiting for by passing the proper tid to pthread_join(). | | | But you should weigh this fact when you are considering using __clone() in your software. |

| | The POSIX Threading and Synchronous Wrappers are a simple set of C++ classes that act as wrappers for the POSIX threading and synchronous API. | | | The POSIX Threading and Synchronous wrappers available here are a great way to understand how the POSIX threading API can be incorparated in an object oriented context such as C++. | | | The main problem is that if the POSIX Read-Write Mutex is used to lock a blocking resource and the resource itself is locked either via system fault or otherwise, the threads in the pending queues of the POSIX Read-Write Mutex may not be able to adequaetly recover. |
