I could be wrong, but "printf()" is going to want to output to a consul, and
I can't see how you are going to capture the output via "popen()" which is
expecting a file pointer. You need to capture the output as a string so
that it can be output to the server as HTML or whatever. However you cannot
return a string from a C executable.
