typedef /*unspecified*/ streamoff; |
The type std::streamoff is a signed integral type of sufficient size to represent the maximum possible file size supported by the operating system. Typically, this is a typedef to long long.
It is used to represent offsets from stream positions (values of type std::fpos). A std::streamoff value of -1 is also used to represent error conditions by some of the I/O library functions.
std::fpos objects is a value of type std::streamoff std::streamoff may be added or subtracted from std::fpos yielding a different std::fpos. std::fpos is implicitly convertible to std::streamoff (the conversion result is the offset from the beginning of the file). std::fpos is constructible from a value of type std::streamoff | represents absolute position in a stream or a file (class template) |
