    off_type offset,
    std::ios_base::seekdir way,

Description

Set the position indicator to the relative specified offset from the base position indicated by the specified way and return the resulting absolute position on success or pos_type(-1) on failure. Optionally specify which area of the stream buffer. The seek operation will fail if which does not include the flag bsl::ios_base::out or if the resulting absolute position is less than zero or greater then length().

Return Value

resulting absolute position, or pos_type(-1) on failure
