Runtime messages with POSIX
The POSIX(ON) runtime option changes both the facility ID and message number for some messages you might see with your C application. Messages that had the facility ID of EDC and ranged in number from 6000 through 6009 before running POSIX(ON) now have a facility ID of CEE and different message numbers.
Table 1 shows the conditions, their facility ID and message number for the different runtime environments. If your C application is coded to respond to specific facility IDs or specific message numbers for processing, then you must check for the proper values depending on the environment.
