Windriver question

Well i have a serious question this time. We have code that we need to compile together and we are curious if there is a way to call other programs from one program, so for example, if i wanna call driver and pneunmatic code from one program, if that can be done how do i do it.

A clearer description would be better, but are you referring to functions/subroutines?
doa();
dob();


doa()
{
something
}
dob()
{
anotherthing
}

This is a rewording of the question here, right?
