Capturing another program's output into current C program...

I am writing a C program that captures another program's output. The
main catch is, the secondary program is called in a loop (the loop goes
up to 10,000 iterations). The output is then stored in a large array.
Lastly, the data from the large array is computed to yield some
statistical information.

My initial attempt was to use pipe and a call to fork to handle output
redirection. This works fine for less than 10 iterations, and simply
does not work with anything over that. I am still an
novice->intermediate programmer and understand that a call to fork
should not be done in a loop. However, I don't know how else I can
approach this issue. I can easily write a perl program that can do the
above spec, but am convinced that a C program would run considerably
faster in this case than the perl could.

Any advice, info, and URL links would be greatly appreciated.

Thanks in advanced,
~Jerome
