SunAda Return Codes

SunAda Return Codes

[Andrew Young]

How does a SunAda program report a return code to Unix?
In C, I would do exit(n) or return(n) from the main() routine, but
I can't find an equivalent package for SunAda.

Thanks in advance for any pointers.

Andy.

All you have to do is make your main a function returning integer instead of 
a procedure, and then RETURN the proper code.

unix.sys_exit(n);

Please note, return values are implementation dependent, and are not defined
anywhere in the LRM.  Making the top-level subprogram a funtion returning an
integer is one solution the compiler writer may choose.  Or it may be included
in a OS isterface package.  I think the POSIX binding do this.

WRT the form of the top-level subprogram, the compiler must at least be able
to handle a procedure with no parameters.  Anything else is at the compiler
writer's discresion.
