Just like C, a packetC function is a discrete subprogram that can be invoked from multiple places in the program text and that returns a value (which may be of type void). The function call or function enable can associate a set of values with a corresponding set of variables declared as the function’s parameters, which act as variables local to the called function. C programmers will find packetC functions to play the same role and operate in a familiar manner. In addition, functions play new roles in packetC in support of parallel processing and scoping for the purposes of data hiding.
