NAME

Glib::Signal - Object customization and general purpose notification

METHODS

integer = Glib->install_exception_handler ($func, $data=undef)

* $func (subroutine)

* $data (scalar)

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)

* $tag (integer)

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.

See gperl_remove_exception_handler() in Glib::xsapi.
