Glib::Signal(3pm)              User Contributed Perl Documentation              Glib::Signal(3pm)



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.
