std::basic_spanbuf<CharT,Traits>::span
From cppreference.com
std::span<CharT> span() const noexcept;

(1) | (since C++23) |
void span( std::span<CharT> s ) noexcept;
|
(2) | (since C++23) |
1) Gets a
span referencing the written area if std::ios_base::out is set in the open mode, or a span referencing the underlying buffer otherwise.2) Makes the
basic_spanbuf perform I/O on the buffer referenced by s. Sets pointers to get area, put area, or both.
| Set bits in open mode (affecting pointers to get area) |

Parameters
| s | - | a std::span that references the user-provided buffer |
Return value
1)
std::span<CharT>(pbase(), pptr()) if std::ios_base::out is set in the open mode, or a std::span<CharT> that references the whole underlying buffer otherwise.2) (none)
