Deallocates the memory block previously allocated at this buffer pointer’s base address.
- Xcode 9.3+
- Swift Standard Library
This buffer pointer’s
base must be
nil or a pointer to a memory block previously returned by a Swift allocation method. If
nil, this function does nothing. Otherwise, the memory must not be initialized or
Pointee must be a trivial type. This buffer pointer’s
count must be equal to the originally allocated size of the memory block.
