:mrdocs:

Allocate a maximally‐aligned memory block from a buffer, without checking capacity.

== Description

Allocate a maximally‐aligned memory block of the specified `size` (in bytes) from the specified `buffer` at the specified `cursor` position. Return the address of the allocated memory block. The `cursor` is set to the first byte position immediately after the allocated memory. The behavior is undefined unless `0 < size`, `buffer` contains sufficient available memory, and `cursor` refers to a valid position in `buffer`.

== Return Value

address of the allocated memory block

== Parameters
