Glib::Signal - Object customization and general purpose notification

integer = Glib->install_exception_handler ($func, $data=undef)
Install a subroutine to be executed when a signal emission traps an exception (a croak or die). $func should return boolean (true if the handler should remain installed) and expect to receive a single scalar. This scalar will be a private copy of $@ which the handler can mangle to its heart's content. Returns an identifier that may be used with "remove_exception_handler". See "gperl_install_exception_handler()" in Glib::xsapi.

Glib->remove_exception_handler ($tag)
Remove the exception handler identified by $tag, as returned by "install_exception_handler". If $tag cannot be found, this does nothing. WARNING: Do not call this function from within an exception handler. If you want to remove your handler during its execution just have it return false.
