pos_type tellp(); | ||
Returns the output position indicator of the current associatedstreambuf object.
Behaves asUnformattedOutputFunction (except without actually performing output). After constructing and checking the sentry object, | (since C++11) |
Iffail()==true, returnspos_type(-1). Otherwise, returnsrdbuf()->pubseekoff(0,std::ios_base::cur,std::ios_base::out).
