strstreambuf* rdbuf() const;		(deprecated in C++98) (removed in C++26)

Returns a pointer to the associated std::strstreambuf, casting away its constness (despite the const qualifier on the member function).

Parameters

(none)

Return value

Pointer to the associated std::strstreambuf, with constness cast away.

Example

Run this code

#include <strstream>
 
int main()
{
    const std::strstream buf;
    std::strstreambuf* ptr = buf.rdbuf();
}
