std::strstreambuf

std::strstreambuf is a std::basic_streambuf whose associated character sequence is a character array, which may be constant (e.g. a string literal), modifiable but not dynamic (e.g. a stack-allocated array), or dynamic, in which case the std::strstreambuf may be allowed to reallocate the array as necessary to accommodate output (e.g. by calling delete[] and new[] or user-provided functions).

# Declarations

class strstreambuf : public std::basic_streambuf<char>

(deprecated in C++98) (removed in C++26)

# Notes

After any call to str() on a stream with a dynamic buffer, a call to freeze(false) is required to allow the strstreambuf destructor to deallocate the buffer when necessary.

strstreambuf has been deprecated since C++98 and removed since C++26. The recommended replacement is std::spanbuf(since C++23).
