getaddrinfo() and freeaddrinfo() fails to compile with /POINTER_SIZE=64, is there a workaround?

[ric...@levitte.org]

Compiling the following test program fails miserably:

---------- 8< [snip] ----------
#include <sys/types.h>
#include <sys/socket.h>
#include <netdb.h>

int main()
{
struct addrinfo *res = NULL;
int ret;

ret = getaddrinfo("localhost", "http", NULL, &res);
freeaddrinfo(res);
}
---------- 8< [snip] ----------

Here's how it compiles:

$ cc /pointer_size=64 foo.c

ret = getaddrinfo("localhost", "http", NULL, &res);
..........^
%CC-W-PTRMISMATCH, In this statement, the referenced type of the pointer value "&res" is "long pointer to struct addrinfo", which is not compatible with "long pointer to struct __addrinfo64".
at line number 10 in file USER:[LEVITTE]FOO.C;2

freeaddrinfo(res);
....^
%CC-W-PTRMISMATCH, In this statement, the referenced type of the pointer value "res" is "struct addrinfo", which is not compatible with "struct __addrinfo64".
at line number 11 in file USER:[LEVITTE]FOO.C;2


Does anyone have a *sensible* workaround? Also, this is really a bug in netdb.h (it doesn't restore pointer size prior to defining 'struct addrinfo'), who can I pester to file a bug report?

Cheers,
Richard

The workaround was too easy...

$ diff sys$login:foo.c
************
File USER:[LEVITTE]FOO.C;3
5 #if __INITIAL_POINTER_SIZE == 64
6 # define addrinfo __addrinfo64
7 #endif
8
9 int main()
******
File USER:[LEVITTE]FOO.C;2
5 int main()
************

Still, netdb.h needs fixing.

Also, if anyone wonders:

$ cc/vers
HP C V7.3-010 on OpenVMS Alpha V8.4

I'll add it to my list for a future VSI release (one of many on my list)

Grand! Thank you :-)
