initialize(from:count:)

Initializes the memory referenced by this pointer with the values starting at the given pointer.

Declaration

func initialize(from source: UnsafePointer<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 must not 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 initialize(from:count:), the region is initialized.
