+@strong{Compatibility Note:} A problem when working with the
+@code{signal} function is that it has a different semantic on BSD and
+SVID system. The difference is that on SVID systems the signal handler
+is deinstalled after an signal was delivered. On BSD systems the
+handler must be explicitly deinstalled. In the GNU C Library we use the
+BSD version by default. To use the SVID version you can either use the
+function @code{sysv_signal} (see below) or use the @code{_XOPEN_SOURCE}
+feature select macro (@pxref{Feature Test Macros}) Generally it should
+be avoided to use this functions due to the compatibility problems. It
+is better to use @code{sigaction} if it is available since the results
+are much more reliable.
+
Here is a simple example of setting up a handler to delete temporary
files when certain fatal signals happen:
(a core dump), and the temporary files may give useful information.
@comment signal.h
+@comment GNU
+@deftypefun sighandler_t sysv_signal (int @var{signum}, sighandler_t @var{action})
+The @code{sysv_signal} implements the behaviour of the standard
+@code{signal} function as found on SVID systems. The difference to BSD
+systems is that the handler is deinstalled after a delivery of a signal.
+
+@strong{Compatibility Note:} As said above for @code{signal}, this
+function should be avoided when possible. @code{sigaction} is the
+preferred method.
+@end deftypefun
+

@deftypefun sighandler_t ssignal (int @var{signum}, sighandler_t @var{action})
