Glib::Signal(3) User Contributed Perl Documentation Glib::Signal(3)
NAME
Glib::Signal - Object customization and general purpose notification
METHODS
integer = Glib->install_exception_handler ($func, $data=undef)
o $func (subroutine)
o $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)
o $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.
