C++ Library - <wstringbuf>
Introduction
It is a stream buffer to read from and write to wstring objects and objects of this class maintain internally a sequence of wide characters that they use as their associated input sequence and/or associated output sequence. The internal sequence can be initialized from a wstring object, or copied to one, using member str.
Definition
Below is definition of std::wstringbuf.
typedef basic_stringbuf<wchar_t> wstringbuf;
Parameters
charT − Character type.
traits − Character traits class that defines essential properties of the characters used by stream objects.
int_type − Integer Type.
Alloc − Type of the allocator object used to define the storage allocation model for the basic_string objects. By default, the allocator class template is used, which defines the simplest memory allocation model and is value-independent.
