-This directory contains two examples: <imore> and <process>. They
-show how you can play with various features of ACE_Process to create
-new processes.
-
-imore:
------
-This example shows how to redirect the output of one process (in our
-case, the parent process) to another process (child process.) This is
-very similiar what a UNIX shell does when we "pipe" command together.
-You can select whether you want to use named pipes or a unnamed pipe.
-
-
-process:
---------
-
-This example shows how to use ACE_Process to "portably" create new
-processes. The ACE_Process_Options class allows applications to
-portably specify path, command-line arguments, environment variable
-values. It also allows applications to set the new process' standard
-handles (stdin, stdout, and stderr). ACE_Process is created with the
-ACE_Process_Options and can be used to perform operations on the
-running process.
-
-Notice that this example uses NT version's UNIX utilities like
-"DATE.EXE," and "ls.exe." You can find where to get them from
-Microsoft's NT page on the Web.
-
-Run the application as ./process -u to get all the command-line
-options.
-
-Here's an example output:
-
-lambada:OS/Process> ./process -a

-Sun May 11 15:06:51 CDT 1997

-// = DESCRIPTION
-// This program demonstrates how to redirect stdout of a parent
-// process to the stdin of its child process using either unnamed pipe
-// or named pipes to relay data to subprocess which runs "more" to
-// display data on the screen. Run imore to see how to use this
-// program.
-//
-// Unfortunately, on Win32, this program doesn't use any pipe at all because
-// using pipes confuses MORE.COM on Win32 and it just acts like "cat" on Unix.
