Sb: #C error trapping
Fm: Dan Charrois 70721,1506
To: all

I have a question regarding C.  In reading a book I have on the language, I
found that there is a global variable errno that contains the latest error
result.  As a result of this, I am led to believe that error trapping in C
(run-time error trapping) is possible as it is for other languages, such as
Basic09.  In a program I wrote, a division by zero error resulted in my
returning back to OS9 with an error message - is there any way to get C to
recognize the error before it happens and avoid going back to OS9, but handle
the error in the way I see best?  such as the onerror command in Basic09...
  Thanks for your replies. .....Dan Charrois
