Xbase Return Codes

Page Updated 2/1/99

Beginning with release 1.8.0a, error processing can be handled using exception processing, or by checking the functions return codes. If you choose exception processing, you will need to compile in the option to do so when you build the library. To see an example of how to use exception processing, examine program dumprecs.cpp.
If you are not using exception processing, it is generally a good idea to check the method return codes to verify an error hasn't occured. Most Xbase DBMS methods return a SHORT return code value which corresponds to a value in this table.
