8.1.4.2 The RXSYSEXIT structure

This structure is used for defining which system exit handlers are
to handle which system exits. The two relevant datatypes are
defined as:

     typedef struct {
           unsigned char *sysexit_name ;
           short sysexit_code ;
     } RXSYSEXIT ;

     typedef RXSYSEXIT *PRXSYSEXIT ;

In this structure, sysexit_name is a pointer to the ASCII NUL
terminated string containing the name of a previously registered
(and currently active) system exit handler. The  sysexit_code
field is main function code of a system exit.

The system exits are divided into main functions and sub-
functions. An exit is defined to handle a main function, and must
thus handle all the sub-functions for that main function. All the
functions and sub-functions are listed in the description of the
EXIT structure.
