I found this document on error handling which is informative: https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/ErrorHandlingCocoa/ErrorObjectsDomains/ErrorObjectsDomains.html#//apple_ref/doc/uid/TP40001806-CH202-CJBGAIBJ While the document discusses NSError (Cocoa) it does bring up the concept of domains. In Listing 1-1 it lists the POSIX domain errors with "13" being a "Permission Denied" error. Table 1-1 lists the various domains with information on which header files contain the error codes. I searched the non-Cocoa headers on opensource.apple.com and found these urls: https://opensource.apple.com/source/xnu/xnu-792/osfmk/mach/kern_return.h https://opensource.apple.com/source/xnu/xnu-4570.71.2/bsd/sys/errno.h.auto.html https://opensource.apple.com/source/CarbonHeaders/CarbonHeaders-18.1/MacErrors.h -- Trevor DeVore ScreenSteps www.screensteps.com _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
