ios::bad

public member function
bool bad ( ) const;

Check if badbit is set

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.
false otherwise.

Basic template member declaration
