NAME¶

std::streamsize - std::streamsize

Synopsis¶

Defined in header <ios>
typedef /*implementation-defined*/ streamsize;

The type std::streamsize is an implementation-defined 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.
