std::basic_osyncstream<CharT,Traits,Allocator>::get_wrapped
From cppreference.com
< cpp | io | basic osyncstream
streambuf_type* get_wrapped() const noexcept; |
||
Returns a pointer to the wrapped std::basic_streambuf, obtained by calling get_wrapped() on the underlying std::basic_syncbuf.
Parameters
(none)
Example
Wrapped buffer can be safely wrapped again in a different synchronized output stream.
Run this code
#include <iostream> #include <syncstream> int main() { std::osyncstream bout1(std::cout); bout1 << "Hello, "; { std::osyncstream(bout1.get_wrapped()) << "Goodbye, " << "Planet!" << '\n'; } // emits the contents of the temporary buffer bout1 << "World!" << '\n'; } // emits the contents of bout1
Output:
Goodbye, Planet! Hello, World!
