StaticRecMutex

Object Hierarchy:

Description:

[ Version ( deprecated_since = "2.32" , replacement = "RecMutex" ) ]
[ CCode ( default_value = "G_STATIC_REC_MUTEX_INIT" , destroy_function = "g_static_rec_mutex_free" , has_type_id = false ) ]
public struct StaticRecMutex

Warning: StaticRecMutex is deprecated since 2.32. Use RecMutex.

A StaticRecMutex works like a StaticMutex, but it can be locked multiple times by one thread.

If you enter it n times, you have to unlock it n times again to let other threads lock it. An exception is the function g_static_rec_mutex_unlock_full: that allows you to unlock a StaticRecMutex completely returning the depth, (i.e. the number of times this mutex was locked). The depth can later be used to restore the state of the StaticRecMutex by calling lock_full. In GLib 2.32, StaticRecMutex has been deprecated in favor of RecMutex.

Even though StaticRecMutex is not opaque, it should only be used with the following functions.

All of the g_static_rec_mutex_* functions can be used even if g_thread_init has not been called. Then they do nothing, apart from trylock, which does nothing but returning true.

Creation methods:

public StaticRecMutex ()
A StaticRecMutex must be initialized with this function before it can be used.

Methods:

public void @lock ()
Locks this.
public void @unlock ()
Unlocks this.
public void lock_full (uint depth)
Works like calling @lock for this depth times.
public bool trylock ()
Tries to lock this.
