I'm not familiar with ARP, but you normally can control the STD* streams
with overrides, e.g. for STDOUT you can redirect the output with OVRDBF
OUTPUT TOFILE(mylib/myfile)
You'll need to execute this command _before_ the file is opened and I
assume you'll also need to experiemnt a little with how far the override
reaches, you do it by the OVRSCOPE and OPNSCOPE-parameters

Subject: [C400-L] Need help with capturing STDOUT


I am facing problem in collecting the output(stdout, stderr) of child
processes on Windows.
I am working in C and using the APR(Apache Portable Runtime) library.
APR's routines for process creation and redirection are being used.

My program calls the perl engine to execute a perl script. Before
creating this child process(perl execution), its stdout and stderr are
redirected to some file. Once this child process is spawned, its outputs
are rightly directed to specified file. This works fine if the called
process writes directly to STDOUT.

The problem occurs if this child process internally calls another
This grand child's output is not getting redirected to that specified
This grand child is getting spawned using "system" in the perl script.
Note however that the output is visible on the console that pops up.

The same code works fine on Linux.

I am using Windows 2000, apr-1.0.1 Release.

Any help would be much appretiated.
