NAME¶
std::basic_streambuf::pubseekpos, - std::basic_streambuf::pubseekpos,
Synopsis¶
pos_type pubseekpos( pos_type pos, (1)
std::ios_base::openmode which = std::ios_base::in | std::ios_base::out );
protected:
virtual pos_type seekpos( pos_type pos, (2)
std::ios_base::openmode which = std::ios_base::in | std::ios_base::out);
Sets the position indicator of the input and/or output sequence to an
absolute
position.
1) Calls seekpos(pos, which) of the most derived class
2) The base class version of this function has no effect. The derived classes
may
override this function to allow absolute positioning of the position
indicator.
Parameters¶
pos - absolute position to set the position indicator to.
defines which of the input and/or output sequences to affect. 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¶
1) The return value of seekpos(pos, which)
2) The resulting absolute position as defined by the position indicator. The
base
class version returns pos_type(off_type(-1)).
