How do I read the results of a system() call in C++?

Question

I\'m using the following code to try to read the results of a df command in Linux using popen.

#include  // file an         


        

Answer 1

To answer the question in the update:

char buffer[1024];
char * line = NULL;
while ((line = fgets(buffer, sizeof buffer, fp)) != NULL) {
    // parse one line of df's output here.
}

Would this be enough?
