NAME

Glib::Log - A flexible logging mechanism

METHODS

scalar = Glib::Log->set_always_fatal ($fatal_mask)

$fatal_mask (scalar)

Glib->critical ($domain, $message)

$domain (string or undef)
$message (string)

Glib->debug ($domain, $message)

$domain (string or undef)
$message (string)

Glib::Log::default_handler ($log_domain, $log_level, $message, ...)

$log_domain (string)
$log_level (scalar)
$message (string)
... (list) possible userdata argument ignored

The arguments are the same as taken by the function for set_handler or set_default_handler.

prev_log_func = Glib::Log->set_default_handler ($log_func, $user_data)

$log_func (subroutine) handler function or undef
$user_data (scalar)

Install log_func as the default log handler. log_func is called for anything which doesn't otherwise have a handler (either Glib::Log->set_handler, or the Glib::xsapi gperl_handle_logs_for),

&$log_func ($log_domain, $log_levels, $message, $user_data)

where $log_domain is a string, and $log_levels is a Glib::LogLevelFlags of level and flags being reported.

If log_func is \&Glib::Log::default_handler or undef then Glib's default handler is set.

The return value from set_default_handler is the previous handler. This is \&Glib::Log::default_handler for Glib's default, otherwise a Perl function previously installed. If the handler is some other non-Perl function then currently the return is undef, but perhaps that will change to some wrapped thing, except that without associated userdata there's very little which could be done with it (it couldn't be reinstalled later without its userdata).

Since: glib 2.6

Glib->error ($domain, $message)

$domain (string or undef)
$message (string)

scalar = Glib::Log->set_fatal_mask ($log_domain, $fatal_mask)

$log_domain (string)
$fatal_mask (scalar)

integer = Glib::Log->set_handler ($log_domain, $log_levels, $log_func, $user_data=undef)

$log_domain (string or undef) name of the domain to handle with this callback.
$log_levels (Glib::LogLevelFlags) log levels to handle with this callback
$log_func (subroutine) handler function
$user_data (scalar)

$log_func will be called as

&$log_func ($log_domain, $log_levels, $message, $user_data);

where $log_domain is the name requested and $log_levels is a Glib::LogLevelFlags of level and flags being reported.

Glib->info ($domain, $message)

$domain (string or undef)
$message (string)

Glib->log ($log_domain, $log_level, $message)

$log_domain (string or undef)
$log_level (scalar)
$message (string)

Glib->message ($domain, $message)

$domain (string or undef)
$message (string)

Glib::Log->remove_handler ($log_domain, $handler_id)

$log_domain (string or undef)
$handler_id (integer) as returned by set_handler

Glib->warning ($domain, $message)

$domain (string or undef)
$message (string)
