Functions | |
DBusCounter * | _dbus_counter_new (void) |
Creates a new DBusCounter. | |
DBusCounter * | _dbus_counter_ref (DBusCounter *counter) |
Increments refcount of the counter. | |
void | _dbus_counter_unref (DBusCounter *counter) |
Decrements refcount of the counter and possibly finalizes the counter. | |
void | _dbus_counter_adjust_size (DBusCounter *counter, long delta) |
Adjusts the value of the size counter by the given delta which may be positive or negative. | |
void | _dbus_counter_adjust_unix_fd (DBusCounter *counter, long delta) |
Adjusts the value of the unix fd counter by the given delta which may be positive or negative. | |
long | _dbus_counter_get_size_value (DBusCounter *counter) |
Gets the current value of the size counter. | |
long | _dbus_counter_get_unix_fd_value (DBusCounter *counter) |
Gets the current value of the unix fd counter. | |
void | _dbus_counter_set_notify (DBusCounter *counter, long size_guard_value, long unix_fd_guard_value, DBusCounterNotifyFunction function, void *user_data) |
Sets the notify function for this counter; the notify function is called whenever the counter's values cross the guard values in either direction (moving up, or moving down). |
DBusCounter and other stuff related to resource limits.
Types and functions related to tracking resource limits, such as the maximum amount of memory/unix fds a connection can use for messages, etc.
void _dbus_counter_adjust_size | ( | DBusCounter * | counter, |
long | delta | ||
) |
Adjusts the value of the size counter by the given delta which may be positive or negative.
Calls the notify function from _dbus_counter_set_notify() if that function has been specified.
