Waht convention to use to return error number?
I want to establish an internal convention for notification of error condition to calling program that is practical and consistent with others, but find there is no clear pattern.
In a control valid, a return .F. or 0 signals an error. In other places, I have seen the return used to indicate the error number and in those cases 0 means no error. I understand a convention in C is to pass a parameter that will return the error number.
What do you all use?
TIA,
Alex
