GLib.pointer_bit_trylock
Description: Reference for GLib.pointer_bit_trylock

### 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.
