Executing a command in C program & Redirecting output to String array 1

[gvidos]

Hi,

I have a C program that invokes the system function every 1 sec (for sampling reasons) and I need to parse the output as shown in stdout,by storing this output to a char array.What I first imagined to be the solution was:

system("tunnel -L -c"
fscanf(stdout,"%s",buffer);

but when control has reached fscanf,the system function has already been completed,having displayed already the output.

How can I possibly capture that output (without re-directing it to a file)?

Thank you,

George
