The short answers is yes with clarification as to what you mean by "same time". Do you mean multi-tasking where the processor appears to be running multiple processes at the same time or do you mean true "same time" where a multi-core processor is required?
With that divergence out of the way check out threads, they allow a single process(or single thread process) to spawn additional processes(or threads/light weight processes).
So yes its possible for a C program to run/spawn more than one process...

This sounds like a candidate for threading. The best thing to do is Google a few thread tutorials, these with some experimenting will determine if threads will work for your program....
