They are all used to modify the signal dispositions. signal() is the
is the old interface from V7 (which only supported unreliable signals).
sigset() is found on System V which supports reliable signals and
sigaction() is the POSIX equivalent. I guess a good advice would be to
stick to the POSIX implementation of signals where ever possible and
stay away from signal() since you never know what is hidden beneath.
