Detailed Description

An DSA public key or public/private key pair that can be used for encryption.

Knows how to encode/decode itself into a string of hex digits for easy transport.

Member Function Documentation

bool WvDSAKey::isok ( ) const [virtual]

By default, returns true if geterr() == 0.

Might be overridden so that isok() == false even though no error code has been specified.

Reimplemented from WvErrorBase.

Definition at line 66 of file wvdsa.cc.

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.

Definition at line 48 of file wverror.h.

Referenced by UniIniGen::commit(), UniFileSystemGen::get(), WvStreamClone::geterr(), WvEncoderStream::isok(), UniConfDaemon::listen(), UniIniGen::refresh(), WvStream::seterr(), and WvMagicCircle::WvMagicCircle().

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.

Definition at line 144 of file wverror.cc.

Referenced by WvUnixListener::accept(), WvTCPListener::accept(), getpem(), WvGlob::set(), WvMagicCircle::WvMagicCircle(), WvPam::WvPam(), WvShmZone::WvShmZone(), and WvTCPListener::WvTCPListener().

void WvErrorBase::noerr ( ) [inline, inherited]

Reset our error state - there's no error condition anymore.

Definition at line 78 of file wverror.h.
