std::streamsize(3) C++ Standard Libary std::streamsize(3) NAME std::streamsize - std::streamsize Synopsis Defined in header <ios> typedef /*implementation-defined*/ streamsize; The type std::streamsize is an implementation-defined signed inte- gral type used to represent the number of characters transferred in an I/O operation or the size of an I/O buffer. It is used as a signed counterpart of std::size_t, simi- lar to the POSIX type ssize_t. Except in the constructors of std::strstreambuf, negative values of std::streamsize are never used. See also gcount returns number of characters extracted by last unformatted input operation (public member function of std::basic_istream<CharT,Traits>) ignore extracts and discards characters until the given character is found (public member function of std::basic_istream<CharT,Traits>) read extracts blocks of characters (public member function of std::basic_istream<CharT,Traits>) write inserts blocks of characters (public member function of std::basic_ostream<CharT,Traits>) http://cppreference.com 2022.07.31 std::streamsize(3)
