std::basic_...buf::seekpos(3)  C++ Standard Libary std::basic_...buf::seekpos(3)

NAME
     std::basic_spanbuf::seekpos - std::basic_spanbuf::seekpos

Synopsis
	protected:

	pos_type   seekpos(   pos_type	 sp,   std::ios_base::openmode	which  =
     (since C++23)

			      std::ios_base::in | std::ios_base::out )
	override;

	Repositions the next pointer to the get and/or put area, if possible, to
     the
	position indicated by sp.

	Equivalent to return seekoff(off_type(sp), std::ios_base::beg, which);.

Parameters
	sp    - stream position, such as one obtained by seekoff() or seekpos()
		defines whether the input sequences,  the  output  sequence,  or
     both are
		affected.  It  can be one or a combination of the following con-
     stants:
	which -
		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().
