This module implements set_sig_handler(), which sets up a signal handler and
|
||
|
|
(optionally) returns an object which causes the signal handler to be reset
|
||
|
|
to the previous value, when it goes out of scope.
|
||
|
|
|
||
|
|
Also implemented is timeout_call() which takes a timeout value and a code
|
||
|
|
reference, and executes the code reference wrapped with an alarm timeout.
|
||
|
|
|
||
|
|
Finally, two convenience routines are defined which allow one to get the
|
||
|
|
signal name from the number -- sig_name(), and get the signal number from
|
||
|
|
the name -- sig_number().
