I'm using gcc v4.0.1 on Ubuntu Linux.
I want to incorporate calls to command line utilities in my C++ for test
purposes. These utilities require parameters, but return no information
to my C++ program.
I can't find the proper function to use. spawn/execute/pexecute?
All I've found in my /usr/include directory is spawn.h, and it includes
a bunch of functions starting with posix_. Before I start playing
around with these "undocumented" functions, could somebody:
- tell me the easiest way.
- the necessary library to link to.
- where any online documentation is located at?
