CGOpenGLDisplayMaskToDisplayID(_:)

Declaration

func CGOpenGLDisplayMaskToDisplayID(_ mask: CGOpenGLDisplayMask) -> CGDirectDisplayID

Parameters

• mask:

  The OpenGL display mask to be converted.

Return Value

The display ID assigned to the specified display mask, or kCGNullDirectDisplay if no display matches the mask.

Discussion

OpenGL sometimes identifies a display using a bitmask with one bit set. This function maps such a display mask to the corresponding display ID. If you pass in a mask with multiple bits set, this function returns a display ID matching one of these bits.
