template< class CharT, class Traits > std::basic_ostream<CharT,Traits>& operator<<( std::basic_ostream<CharT,Traits>& ost, std::thread::id id ); | (since C++11) |
Writes a textual representation of a thread identifier id
to the output stream ost
.
If two thread identifiers compare equal, they have identical textual representations; if they do not compare equal, their representations are distinct.
ost | - | output stream to insert the data into |
id | - | thread identifier |
