std::basic_spanbuf<CharT,Traits>::setbuf - cppreference.com (original) (raw)

Makes the basic_spanbuf perform I/O on the buffer [s, s + n). Equivalently calls this->span(std::span<CharT>(s, n)) and then returns this.

Set bits in open mode(affecting pointers to get area)	Return value after setting
eback()	gptr()	egptr()
std::ios_base::in	s	s	s + n
Set bits in open mode(affecting pointers to put area)	Return value after setting
pbase()	pptr()	epptr()
std::ios_base::out &&	s	s	s + n
std::ios_base::out && std::ios_base::ate	s	s + n	s + n

This function is protected virtual, it may only be called through pubsetbuf() or from member functions of a user-defined class derived from std::basic_spanbuf.

[edit] Parameters

[edit] Return value

this

[edit] Notes

The deprecated stream buffer std::strstreambuf or the boost.IOStreams device boost::basic_array can also implement I/O buffering over a user-provided char array.
