    std::ios_base::openmode which = bsl::ios_base::out) override;

Description

Set the position indicator to the relative specified offset from the base position indicated by the specified fixedPosition 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 than the value returned by length.

Return Value
