NAME

6       Glib::Signal -  Object customization and general purpose notification
7

METHODS

9   integer = Glib->install_exception_handler ($func, $data=undef)
10       ·   $func (subroutine)
11
12       ·   $data (scalar)
13
14       Install a subroutine to be executed when a signal emission traps an
15       exception (a croak or die).  $func should return boolean (true if the
16       handler should remain installed) and expect to receive a single scalar.
17       This scalar will be a private copy of $@ which the handler can mangle
18       to its heart's content.
19
20       Returns an identifier that may be used with "remove_exception_handler".
21
22       See "gperl_install_exception_handler()" in Glib::xsapi.
23
24   Glib->remove_exception_handler ($tag)
25       ·   $tag (integer)
26
27       Remove the exception handler identified by $tag, as returned by
28       "install_exception_handler".  If $tag cannot be found, this does
29       nothing.
30
31       WARNING:  Do not call this function from within an exception handler.
32       If you want to remove your handler during its execution just have it
33       return false.

35       See "gperl_remove_exception_handler()" in Glib::xsapi.
