popen returns a standard i/o stream so you just read from it exactly
like a file! Make sure when you invoke it you use 'r'. eg

#include <stdio.h>
int main( void )
{   FILE *pipe;
    char c;
    if( ! ( pipe = popen("ls -l", "r") ) )
    { perror("ls -l");
      return;
    }

   while( ( c = fgetc(pipe) ) != EOF )
   printf("%c", c);
   return 0;
}
