Hello list,

when using socketpair(2)  on my FreeBSD 6.1-RELEASE-p1 box i get this error:
"socketpair: Operation not supported"

And here is the source of my pretty simple socketpair(2) program:
---- START ----
#include <sys/types.h>
#include <sys/socket.h>
#include <stdio.h>
#include <errno.h>

int main(void) {
int sv[2], err;
err = socketpair(AF_INET, SOCK_STREAM, 0, (int*)&sv);
if(err == -1) {
        return -1;

return 0x0;
---- END ----

Any comments ?
