Description

This function attempts to obtain a character buffer with space for at least `n` characters. Upon success, a pointer to the beginning of the buffer is returned. Ownership is not transferred; the caller should not attempt to free the storage. The buffer shall remain valid until `this` is destroyed.

This function may only be called once. After invoking the function, the only valid operation is destruction.
