/*

|
||||
Implementation for Windows
|
||||
|
||||
|
||||
On windows, a thread is created to wait for data on each pipe. The
|
||||
threads are synchronized with the main thread to simulate the use of
|
||||
a UNIX-style select system call.
|
||||
|
||||
|
||||
On Windows9x platforms, a small WIN32 console application is spawned
|
||||
in-between the calling process and the actual child to be executed.
|
||||
This is to work-around a problem with connecting pipes from WIN16
|
||||
console applications to WIN32 applications.
|
||||
|
||||
|
||||
For more information, please check Microsoft Knowledge Base Articles
|
||||
Q190351 and Q150956.
