moveInitialize(from:count:)

Moves instances from initialized source memory into the uninitialized memory referenced by this pointer, leaving the source memory uninitialized and the memory referenced by this pointer initialized.

Declaration

func moveInitialize(from source: UnsafeMutablePointer<Pointee>, count: Int)

Parameters

  • source:

    A pointer to the values to copy. The memory region source..<(source + count) must be initialized. The memory regions referenced by source and this pointer may overlap.

  • count:

    The number of instances to move from source to this pointer’s memory. count must not be negative.

Discussion

The region of memory starting at this pointer and covering count instances of the pointer’s Pointee type must be uninitialized or Pointee must be a trivial type. After calling moveInitialize(from:count:), the region is initialized and the memory region source..<(source + count) is uninitialized.
