/*
|
|
* w9xpopen.c
|
|
*
|
|
* Serves as an intermediate stub Win32 console application to
|
|
* avoid a hanging pipe when redirecting 16-bit console based
|
|
* programs (including MS-DOS console based programs and batch
|
|
* files) on Window 95 and Windows 98.
|
|
*
|
|
* This program is to be launched with redirected standard
|
|
* handles. It will launch the command line specified 16-bit
|
|
* console based application in the same console, forwarding
|
|
* it's own redirected standard handles to the 16-bit child.
|
|
|
|
* AKA solution to the problem described in KB: Q150956.
