virtual pos_type seekpos(pos_type sp,
                         std::ios_base::openmode which = std::ios_base::in | std::ios_base::out );

Repositions std::basic_streambuf::gptr and/or std::basic_streambuf::pptr, if possible, to the position indicated by sp

Effectively executes seekoff(off_type(sp), std::ios_base::beg, which)

Parameters

sp - stream position, such as one obtained by seekoff() or seekpos()
which - defines whether the input sequences, the output sequence, or both are affected. It can be one or a combination of the following constants:
Constant Explanation
in affect the input sequence
out affect the output sequence

Return value

sp on success or pos_type(off_type(-1)) on failure.

Notes

seekpos() is called by std::basic_streambuf::pubseekpos, which is called by the single-argument versions of std::basic_istream::seekg and std::basic_ostream::seekp
