GLib.pointer_bit_trylock (original) (raw)

Function

GLibpointer_bit_trylock

since: 2.30

Declaration [src]

gboolean
g_pointer_bit_trylock (
  void* address,
  gint lock_bit
)

Description [src]

This is equivalent to g_bit_trylock(), but working on pointers (or other pointer-sized values).

For portability reasons, you may only lock on the bottom 32 bits of the pointer.

While address has a volatile qualifier, this is a historical artifact and the argument passed to it should not be volatile.

Available since: 2.30

Parameters

address

Type: void*

A pointer to a #gpointer-sized value.

The data is owned by the caller of the function.

lock_bit

Type: gint

A bit value between 0 and 31.

Return value

Type: gboolean

TRUE if the lock was acquired.
