DLM's and C code [message #28749]

A somewhat IDL related question.
I am trying to link in some C code via a DLM. I use a wrapper routine to
handle the call from IDL and manipulate the args and return data. Within the
wrapper, I call C functions linked in through another DLL.

What is the best way to handle errors while deeply nested within layers of C
functions.? The ANSI C code I am using essentially had exit(1) calls for
major errors. Is there an IDL_ function (like say an exit handler) I can
call to cleanly return to IDL rather than a trying to modify the call stack
and get back to the IDL wrapper function to perform something like a return
IDL_StrToSTRING("ERROR") ;

Thanks
