pos_type seekpos( pos_type sp, std::ios_base::openmode which =
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);.
Contents
[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() .
