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 constants:
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().
