The function returns
true if the
badbit stream's error flag has been set by a previous i/o operation. This flag is set by standard input operations when an error that caused the loss of integrity of the stream happened.
Notice that this function is not the exact opposite of
good, which checks whether none of the error flags (
eofbit,
failbit and
badbit) are set, and not only the
badbit flag.
Parameters
none
Return Value
true if
badbit stream's state flag is set.
