Thanks to the help and advice of the good folks on this list, I have
managed to solve my C compiler problem. Turns out that I need to do a
#define _NO_NEW_FUNC_CHECK
at the beginning of the code. That tells the C compler (C/C++ for z/VM,
btw) to actually include the correct code to invoked the "getaddrinfo"
function, instead of generating a dummy external structure with the name
of "getaddrinfo". The dummy structure was the actual source of the error
message the C compiler produced.
Unfortunately, the _NO_NEW_FUNC_CHECK directive is not documented
anywhere in either the C or LE manuals, and I don't have a warm fuzzy
feeling about having to use it. Maybe some one from C or LE development
can add to my understanding of why it's there and what it's meant to do...
The good news is that the code now compiles, loads and runs as I expect
it to.
Thanks again, and have a good one.

Hi Dave,
Have you tried c89? I cut and paste your code and compiled with

Subject
a C language question....
I know that this is the z/VM forum, but I have a question about
compiling a C program on CMS, so I'm hoping someone here might know the
answer.....
I've written a short C test program that invokes the new "getaddrinfo" C
library function. However, the z/VM C/C++ compiler complains with the
following error message when I attempt to compile my test program:
> #define _OPEN_SYS_SOCK_IPV6
> #include <netdb.h>
> #include <sys/socket.h>
> #include <stdio.h>
> #include <errno.h>

Can anyone tell me what I'm doing wrong (besides the obvious fact that I
am reduced to using C as a programming language, which has to be one of
the worst tools ever devised..the use of C has set back good software
development by 20 years, imho.)
Thanks for any help and have a good one.
