DataLink error codes

Hello Informix users, My project team is developing an INFORMIX based system in which users access an Informix database on a Sun Sparcstation from a Macintosh workstation across an ethernet network. We use Wingz and DataLink as the front end to the database. My question is related to error handling. There seem to be two levels of error codes in DataLink. The high level codes are defined in the DB script (e.g. A_ERROR). There also seems to be a lower level of error codes accessible through the DBGetErr() function. I am searching for a list of the possible values returned by DBGetErr(). So far, I know that if DBGetErr() returns -27009, it means that sqlexecd is not running. I have looked through the DataLink and INFORMIX-NET documentation and have yet to find a list of error codes which contains the above value. Perhaps someone can point me in the right direction? Any information is appreciated! Brian O'Sullivan m21520@mwvm.mitre.org MITRE Corp. NASA HQ site Washington, DC
