Repositions the file pointer, if possible, to the position indicated by
If the associated file is not open (is_open()==false), fails immediately.
If the file is open for writing, first writes the put area and any unshift sequences required by the currently imbued locale, using Template:rlpf
Then repositions the file pointer, as by calling std::fseek
If the file is open for reading, updates the get area if necessary.
|sp||-||file position obtained by Template:rlpf or Template:rlpf called earlier on the same file|
|which||-|| defines which of the input and/or output sequences to affect. It can be one or a combination of the following constants:
sp on success or pos_type(off_type(-1)) on failure.
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
