Hello,
I tried to use the mig4nto library to get my old QNX4 programs running on
QNX 6.1. It works fine on local node but it cannot locate global names on
network. I know that for the name_attach()/name_open() functions the
global names aren’t supported yet. Are the global names working with
qnx_name_attach()/qnx_name_locate() functions from the mig4nto library?
Thank you,
Jan.

It looks like the qnx_name_attach() only view the local nid/0 as the only
valid one.

You should contact your sales rep. for more information on ETA.

Here is a little sample how to do global_name_open() yourself.
-xtang
#include <sys/dispatch.h>
#include <dirent.h>
#include <errno.h>
#include <fcntl.h>
#include <share.h>
int global_name_open(const char *name, int flags)
{
int fd;
DIR *dir;
struct dirent *dent;
char *newname;
if ((fd = name_open(name, 0)) != -1 || (flags & NAME_FLAG_ATTACH_GLOBAL) == 0) {
return fd;
}
if ((dir = opendir("/net")) == NULL) {
errno = ENOENT;
return -1;
}
while (dent = readdir(dir)) {
newname = alloca(strlen("/net/") + strlen(dent->d_name) +
strlen("/dev/name/global/") + strlen(name) + 1);
if (!newname) {
errno = ENOMEM;
return -1;
}
sprintf(newname, “/net/%s/dev/name/global/%s”, dent->d_name, name);
fd = _connect(_NTO_SIDE_CHANNEL, newname, 0, O_RDWR, SH_DENYNO,
_IO_CONNECT_OPEN, 1, _IO_FLAG_RD | _IO_FLAG_WR,
_FTYPE_NAME, 0, 0, 0, 0, 0, 0);
if (fd != -1) {
closedir(dir);
return fd;
}
}
closedir(dir);
errno = ENOENT;
return -1;
}
Steve: Is this documented? If so, where?

I don’t know if it is documented anywhere, but it looks useful. I’ll see
where we can put it.
