typedef /*unspecified*/ streamsize;

的类型std::streamsize是一个带符号的整数类型，用来表示在一个I / O操作的I / O缓冲器的大小传输的字符的数目。它是用来作为一个符号的对应物std::size_t，类似于POSIX类型ssize_t.

Original:

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.
