Function

GObjectsignal_handlers_unblock_matched

Declaration 

guint
g_signal_handlers_unblock_matched (
  GObject* instance,
  GSignalMatchType mask,
  guint signal_id,
  GQuark detail,
  GClosure* closure,
  gpointer func,
  gpointer data
)

Description

Unblocks all handlers on an instance that match a certain selection criteria.

The criteria mask is passed as a combination of GSignalMatchType flags, and the criteria values are passed as arguments. A handler must match on all flags set in mask to be unblocked (i.e. the match is conjunctive).

Passing at least one of the G_SIGNAL_MATCH_ID, G_SIGNAL_MATCH_CLOSURE, G_SIGNAL_MATCH_FUNC or G_SIGNAL_MATCH_DATA match flags is required for successful matches. If no handlers were found, 0 is returned, the number of unblocked handlers otherwise. The match criteria should not apply to any handlers that are not currently blocked.

Support for G_SIGNAL_MATCH_ID was added in GLib 2.78.
