Eror Codes

Chapter Updated 1/31/23


Error Codes and Error Processing

Alomost all Xbase64 methods and functions return and xbInt16 return code, which is zero or positive on success and negative if an error condition occurs.

As of the 4.x.x release, the library has been extensively updated to use exception processing and most error conditions will result in a mesage written to the logfile if logfile processing is enabled. The error routines typically write two values to the logfile, an error code value and an iErrorStop value which identifies where exactly in the library code the error occurred.

Error codes are defined in the xbretcod.h file.
