Returns the message class associated with the error index provided. An index value of 1 will retrieve the lowest-level (for example, the oldest) message that is associated with the error handle. An index value of "cwbSV_GetErrCount()'s returned errorCount" will retrieve the top-level (for example, the most recent) message associated with the error handle.
unsigned int CWB_ENTRY cwbSV_GetErrClassIndexed( cwbSV_ErrHandle errorHandle, unsigned long errorIndex, unsigned long *errorClass);
The following list shows common return values.
Valid index values are from 1 to cwbSV_GetErrCount()'s return value. Index values less than 1 act as if 1 was passed. Index values greater than cwbSV_GetErrCount() act as if errorCount was passed.
