Detailed Description

template<typename _StateT>
class std::fpos< _StateT >

The standard places no requirements upon the template parameter StateT. In this implementation StateT must be DefaultConstructible, CopyConstructible and Assignable. The standard only requires that fpos should contain a member of type StateT. In this implementation it also contains an offset stored as a signed integer.

Parameters:

StateT

Type passed to and returned from state().
