(2) | (since C++23) |
1) Gets a
span referencing the written area if std::ios_base::out is set in the open mode of the wrapped std::basic_spanbuf, or a span referencing the underlying buffer otherwise.2) Makes the wrapped std::basic_spanbuf perform I/O on the buffer referenced by
s.Parameters
| s | - | std::span referencing the storage to be use as the new underlying buffer of stream |
Return value
1) A std::span referencing the underlying buffer or written area, depending on the open mode of the wrapped std::basic_spanbuf.
2) (none)
