seekpos(
    pos_type position,
    std::ios_base::openmode which = bsl::ios_base::in
                                                         | bsl::ios_base::out) override;

== Description

Set the position indicator to the specified `position` and return the resulting absolute position on success or pos_type(‐1) on failure. Optionally specify `which` area of the stream buffer. The `seekpos` operation will fail if `which` does not include the flag `bsl::ios_base::out` or if `position` is less then zero or greater than `length()`.

== Return Value

resulting absolute position, or `pos_type(‐1)` on failure

== Parameters
