std::streamsize

Defined in header <ios>
typedef /*unspecified*/ streamsize;

The type std::streamsize is a signed integral 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, similar to the POSIX type ssize_t.

Except in the constructors of std::strstreambuf, negative values of std::streamsize are never used.
