Functional Return 

pin                   16-bit signed integer (assigned functional return) 

                      Returns the PIN of the specified child process.

Parameters 

numchild              16-bit signed integer by value (required) 

                      Passes a number indicating which child's PIN
                      GETPROCID returns.  The value of numchild 
                      corresponds to the order of creation of the current
                      children of the calling process, as follows:

                         Value    Meaning 

                          <=1     PIN of the oldest child process

                      2           PIN of second oldest child process
                      .           .
                      .           .
                           .      .

                           n      PIN of the most recently created child process (where
                                  n is the number of children currently in existence)

                          >n      A value greater than the number of children in
                                  existence, returns a zero.
