According to POSIX.1/SUSv3 the pid argument to kill(1) has the same
semantics as kill(3), which includes the following:
        If pid is negative, but not -1, sig shall  be  sent  to  all
        processes (excluding  an unspecified set of system processes)
        whose process group ID is equal to the absolute value of pid,
        and for which the process has permission to send a signal.

So while there is no killpg(1), kill(1) will do the job just fine.
