| ios::good |
public member function |
Check if the state of the stream is good for i/o operations.
The function returns true if none of the stream's error flags (eofbit, failbit and badbit) are set.
Notice that this function is not the exact opposite of bad(), which only checks whether the badbit error flag is set.
The error flags can be checked independently by using any of the member functions eof, fail and bad.
The value returned by this function is the same as the result of evaluating:
(rdstate() == 0)
Parameters
none
Return Value
true if none of the stream's state flags are set.
false if any of the stream's state flags are set (
badbit,
eofbit or
failbit).
