.SH "Detailed Description"
.PP 
Class error_condition
.PP
This class represents error conditions that may be visible at an API boundary\&. Different \fCerror_code\fP values that can occur within a library or module might map to the same \fCerror_condition\fP\&.
.PP
An \fCerror_condition\fP represents something that the program can test for, and subsequently take appropriate action\&.
