running another program from a C++ program

[Lorenzo Bettini]

Hi

I'd like to run a program from a running C++ program (i.e. spanning a
new process) and would like to have access to its standard input and
standard output and error (possibily via streams).

I know about the popen posix function but that's not very flexible...
is there a C++ way?

thanks in advance
Lorenzo

No. All those things are platform-specific.

Nope, it's system dependent. I'd recommend either comp.unix.programmer
(based on your posix comment), or comp.windows.ms.programmer for win32.

Indeed I found

since I'm using QT

thanks anyway
