pos_type pubseekpos( pos_type pos, std::ios_base::openmode which=std::ios_base::in\|std::ios_base::out);	(1)
protected: virtual pos_type seekpos( pos_type pos, std::ios_base::openmode which=std::ios_base::in\|std::ios_base::out);	(2)

Sets the position indicator of the input and/or output sequence to an absolute position.

1) Callsseekpos(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.

[edit]Parameters

pos - absolute position to set the position indicator to

which

defines which of the input and/or output sequences to affect. 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

1) The return value ofseekpos(pos, which).

2) The resulting absolute position as defined by the position indicator. The base class version returnspos_type(off_type(-1)).

[edit]Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR	Applied to	Behavior as published	Correct behavior
LWG 55	C++98	the base class version of`seekpos` returned an undefined invalid stream position	returnspos_type(off_type(-1))
