Can someone point me to an article/HowTo on running a console based program from a KDevelop Qt app and how to parse the output of that console program.

Thank you

You'll want to look at various system calls (assuming you don't want this app to be portable to non-UNIX systems). Look at:

exec, execve, etc.
fork
popen (I think this is the one you want)

They all have manual pages.

Will these system calls run on a mac? j/w

All of those functions are designed for only read or write from what I understand. I need to execute a program and read the output of that program so that i can parse it. At the same time i need to issue commands to that program.

Any idea how I would do this??

what language is it in? parsing text is nasty nasty nasty in c, but an absolute dream in perl....

popen executes a program and gives you a pipe which you can use to write to its standard input and read from its standard output (if you pass "r+" as the second argument), which presumably would allow you to issue commands and parse the output of the program (although as acid says, this could be nasty in C).

popen would exist in Mac OSX, I doubt it would in the earlier (non-UNIX) versions. You might find Qt/KDE has some classes/functions which let you do the same kind of thing as popen.

I'm using Qt/KDE for this project. I will look to see if there are any existing classes/functions to do this. Otherwise i will have to reread the popen documentation.
I have been reading a lot and found a couple of other possibilities, has anyone heard of Pstreams or Dynac++?

"In the simplest case, a PStreams class is like a C++ wrapper for the POSIX.2 functions popen(3) and pclose(3), using C++ IOStreams instead of C's stdio library." http://pstreams.sourceforge.net/

Dncac++ is also a class written for multithreading.

Let me know what you think of these or if anyone has tried them.

Turns out both KDE and Qt have classes for this: QProcess and KProcess. I should have known they have classes for everything else.

I'll let you know how it goes.

Hello

I'm new to programming under Linux and KDeveloper.
I hope someone can help me.

I have tried to add the kprocess.h header to a project in KDeveloper 2.1.5, but KDeveloper can not find the it. I have tried to add the include path and running configure, but to no help.

How do I add the include path to kd3 and qt3 ?
