@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:

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.
