Create an empty stream buffer with sufficient initial capacity to accommodate up to the specified numElements characters without subsequent reallocation. If numElements == 0, an implementation‐defined initial capacity is used. Optionally specify a basicAllocator used to supply memory. If basicAllocator is 0, the currently installed default allocator is used.
