[Ecls-list] How do I get back errors

[David Creelman]

Hi,

I find myself entering strings incorrectly, etc when interacting with
ECL, and I see that there are some error functions in externals.h. 

If I entered a CL string incorrectly, which function do I use to get
back an error ? Is there a catch all error report function ?

... Or should I be checking more often for Cnil on return?

Thanks
David
