'' The POSIX 1003.1-2001 standard defines an application programming
|
|
interface (API) for writing multithreaded applications. This
|
|
interface is known more commonly as pthreads. A good number of
|
|
modern operating systems include a threading library of some kind:
|
|
Solaris (UI) threads, Win32 threads, DCE threads, DECthreads, or any
|
|
of the draft revisions of the pthreads standard. The trend is that
|
|
most of these systems are slowly adopting the pthreads standard API,
|
|
with application developers following suit to reduce porting woes.
|
|
|
|
Woe32 does not, and is unlikely to ever, support pthreads natively.
|
|
This project seeks to provide a freely available and high-quality
|
|
solution to this problem.
