Non-member functions

swap(std::basic_spanbuf) (C++23)

 

void swap( basic_spanbuf& rhs );		(since C++23)

Swaps the state of *this and rhs.

Calls std::basic_streambuf<Char, Traits>::swap(rhs), swaps the open mode of *this and rhs, and then makes them use the underlying buffer of each other.

Parameters

rhs

-

another basic_stringbuf

Return value

(none)

Exceptions

May throw implementation-defined exceptions.

Notes

This function is called automatically when swapping stream objects, it is rarely necessary to call it directly.
