some storage or retrieval has failed but that the stream is still in a usable state.

Returns a nonzero integer if the bad bit has been set. Normally this indicates that a severe
error has occurred from which recovery is probably impossible.
virtual int
good() = 0;
Returns a nonzero integer if no error bits have been set.
virtual int
rdstate() = 0;
Returns the current error state.
virtual void
clear(int v=0) = 0;
