Hello Jay,
t.hoshi correctly said that it is a warning only. For a no error case, you must have error code 0 and error status False.
As t.hoshi said,"This can be confirmed by clicking help on the toolbar and clicking on something along the lines of error description or explanation of error."
For error case, you can not differentiate between fatal error and non-fatal error programatically. The difference between the two is as follows:
A fatal error is an error which causes a program to abort - and thus may return the user to the operating system. When this happens, data that the program was processing may be lost. A fatal error occurs typically in any of these cases:
- An illegal instruction has been attempted
- Invalid data or code has been accessed
- The privilege level of an operation is invalid
- A program attempts to divide by zero. (Only for integers; with the IEEE floating point standard, this creates an infinity instead)
A non-fatal error is an error in a computer program which does not result in termination of execution, but which causes the processor to invent an interpretation, issue a warning, and continue processing.
