std::basic_spanbuf<CharT,Traits>::seekpos - cppreference.com (original) (raw)
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);.
[edit] 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 |
[edit] Return value
sp on success or pos_type(off_type(-1)) on failure.
[edit] 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().
