Function

xpc_data_create(_:_:)

Creates an XPC object representing buffer of bytes.

Declaration

func xpc_data_create(_ bytes: UnsafeRawPointer?, _ length: Int) -> xpc_object_t

Parameters

bytes

The buffer of bytes which is to be boxed. You may create an empty data object by passing NULL for this parameter and 0 for the length. Passing NULL with any other length will result in undefined behavior.

length

The number of bytes which are to be boxed.

Return Value

A new data object.

Discussion

This method will copy the buffer given into internal storage. After calling this method, it is safe to dispose of the given buffer.
