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) |
