virtual bool WvErrorBase::isok | ( | ) | const [inline, virtual, inherited] |
By default, returns true if geterr() == 0.
Might be overridden so that isok() == false even though no error code has been specified.
Reimplemented in WvEncoderStream, WvReadLineStream, WvTCPConn, WvNullListener, WvFdStream, WvLog, WvStream, WvStreamClone, WvSSLStream, IWvStream, WvDBusServer, WvDSAKey, WvTimeStream, WvBufStream, WvListener, WvTimeoutStream, WvIStreamList, and _WvConStream.

virtual int WvErrorBase::geterr | ( | ) | const [inline, virtual, inherited] |
If isok() is false, return the system error number corresponding to the error, -1 for a special error string (which you can obtain with errstr()) or 0 on end of file.
If isok() is true, returns an undefined number.
Reimplemented in WvStreamClone, and WvDBusServer.

void WvErrorBase::seterr | ( | int | _errnum | ) | [virtual, inherited] |
Set the errnum variable -- we have an error.
If called more than once, seterr() doesn't change the error code away from the previous one. That way, we remember the _original_ cause of our problems.
Subclasses may want to override seterr(int) to shut themselves down (eg. WvStream::close()) when an error condition is set.
Note that seterr(WvString) will call seterr(-1).
Reimplemented in WvStream.
