By default, returns true if geterr() == 0. | |
virtual int | geterr () const |
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. | |
virtual WvString | errstr () const |
virtual void | seterr (int _errnum) |
Set the errnum variable – we have an error. | |

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

WvString | errstring |
A class for managing error numbers and strings.
It can have either a system error value, like those defined in errno.h, or an arbitrary error string. In either case, it can return a string representation of the error message.
This object is most useful for using as a base class of your own class, for historical/backwards compatibility reasons. Consider using a WvError instead, and making it a member of your class instead of a parent.

By default, returns true if geterr() == 0.
Might be overridden so that isok() == false even though no error code has been specified.

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.

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).
