std::basic_spanbuf<CharT,Traits>:: seekpos

protected : pos_type seekpos ( pos_type sp, std:: ios_base :: openmode which = std:: ios_base :: in | std:: ios_base :: out ) override ;		(since C++23)

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()
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() .
