pointerBitLockMaskPtr
fun pointerBitLockMaskPtr( ptr: <Error class: unknown class>? = null, lockBit: <Error class: unknown class>, set: Boolean, preserveMask: <Error class: unknown class>, preservePtr: <Error class: unknown class>? = null): <Error class: unknown class>?(source)
This mangles @ptr as g_pointer_bit_lock() and g_pointer_bit_unlock() do.
Return
the mangled pointer.

2.80
Parameters
ptr
the pointer to mask
lockBit
the bit to set/clear. If set to G_MAXUINT, the lockbit is taken from @preserve_ptr or @ptr (depending on @preserve_mask).
set
whether to set (lock) the bit or unset (unlock). This has no effect, if @lock_bit is set to G_MAXUINT.
preserveMask
if non-zero, a bit-mask for @preserve_ptr. The
preservePtr
if @preserve_mask is non-zero, the bits from this pointer are set in the result.
