Well, as you are writing a C-program (or at least you didn't say otherwise) I suggest using popen(3).

yes, what language is it? what have you written so far? (just to give some details to be able to give some hints).

Given that you've said "RPC" this points to a specific language, neither C, nor any scripting one.

As others have stated, you should be more clear about this language and also share a clip of the code you have written for this. Otherwise it is difficult for members to be able to help you because we would be guessing at exactly what best will help you.
