Suppress console output from external code

[wapoc]

Hi,

Apologies if this is a daft question but I'm fairly new to this. My Java code uses the JNI to call a C++ DLL wrapper which I wrote, that in turns calls some pre-written C++ code from elsewhere.

The latter does a lot of information output to the console from which the Java program was started. I'd like to stop this (redirect it to null or a file) without modifying that code, but don't know if I can.

Any ideas? Cheers!

Rob

Windows: yourprog.exe 2> nul > nul
UNIX: ./yourprog 2> /dev/null > /dev/null

Thanks, but I'm aware of how you can pipe output using the console, which is exactly the effect that I'm after. However this is a DLL, hence the problem...

Create an additional .exe, that does nothing, but calls your .dll code. In your main application call this external .exe using something like
system("calldll.exe > logfile.log");
and analyse contents of file logfile.log then.
Windows tool rundll32.exe could be usefull too.
