Hello friends,
from my C-Programm I make a SystenCall like this :
tmp=system(answer.sc)

answer.sc is a ShellScrip witch returns a string like "Hello"

How can I use this string "hello" in my C-Programm.

I think the script needs an "exit value"

But I don´t know how to use it.

Any solutions ???

Many thanks !

Hi Peter,

You talk about: tmp=system(echo "thi is string") or tmp=system(`execute same`).

Hello Gustavo,
thank you for post reply. I think I have not find the right words for my question.
I try it later with some examples for better understanding.

Thanks

I think you should use _popen() instead of system().

FILE *f;
char output[256];

f = _popen("answer.sc", "r");

if ( f != NULL) output = fgets(output, 256, f);

_pclose(f);
