NAME

METHODS

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