Create a basic_ostringstream object. Use the specified initialString as the value that will be returned by a call to str prior to any streaming operations performed on this object. rdbuf is created using ios_base::out. Optionally specify the allocator used to supply memory. If allocator is not supplied, a default‐constructed object of the (template parameter) ALLOCATOR type is used. If the ALLOCATOR argument is of type bsl::allocator (the default), then allocator, if supplied, shall be convertible to bslma::Allocator *. If the ALLOCATOR argument is of type bsl::allocator and allocator is not supplied, the currently installed default allocator will be used to supply memory.
