createInplaceUninitializedBuffer(

----

== Description

Return a shared pointer with an in‐place representation holding a newly‐created uninitialized buffer of the specified `bufferSize` (in bytes). Optionally specify a `basicAllocator` used to supply memory. If `basicAllocator` is 0, the currently installed default allocator is used. The behavior is undefined unless `0 < bufferSize`.

== Return Value

shared pointer to a newly allocated uninitialized buffer
