# load(fromByteOffset:as:)

Returns a new instance of the given type, read from the buffer pointer’s
raw memory at the specified byte offset.

```
func load<T>(fromByteOffset offset: Int = 0, as type: T.Type) -> T
```

## Parameters

`offset`

The offset, in bytes, into the buffer pointer’s memory at
which to begin reading data for the new instance. The buffer pointer
plus `offset` must be properly aligned for accessing an instance of
type `T`. The default is zero.

`type`

The type to use for the newly constructed instance. The memory
must be initialized to a value of a type that is layout compatible
with `type`.

## Return Value

A new instance of type `T`, copied from the buffer pointer’s
memory.

## Discussion

The memory at `offset` bytes from this buffer pointer’s `baseAddress`
must be properly aligned for accessing `T` and initialized to `T` or
another type that is layout compatible with `T`.

You can use this method to create new values from the buffer pointer’s
underlying bytes. The following example creates two new `Int32`
instances from the memory referenced by the buffer pointer `someBytes`.
The bytes for `a` are copied from the first four bytes of `someBytes`,
and the bytes for `b` are copied from the next four bytes.

```
let a = someBytes.load(as: Int32.self)
let b = someBytes.load(fromByteOffset: 4, as: Int32.self)
```

The memory to read for the new instance must not extend beyond the buffer
pointer’s memory region—that is, `offset + MemoryLayout<T>.size` must
be less than or equal to the buffer pointer’s `count`.
