QuestionHow to redirect command output - general reference wanted... Pin

This is somewhat a dupe, so if it bothers you...( I am not allowed to give instructions ...)

I am asking for generic / general help in capturing Linux command output.

I am going to use this as an example:

system("hcitool dev | cut -sf3 ");


I know what is does - that is NOT of my concern..

I can see the result in (Qt) console...

I do not know HOW - what "hidden" code (std??) put
the actual result of the call onto console

and

how can I redirect such call for my purpose ?

I did RTFM for "system" and found NO references , or missed them,
on how to capture THE actual output of the command.

that said - what would be SUCCESSFUL phrase to ask Mrs Google to
give me a general Linux resource ( text book ?) to cover

"standard output / input / error "
and

how to figure out if the command uses

"standard output / input / error "

and how to access it in C/C++

..all this just for learning purpose

CHEERS
