mkfifo System call is failing

[Thomas Mereness]

I'm porting our app to Itanium and the mkfifo call is failing even though the parms look OK and worked on our older HP-UX systems. We first call pipe(...), which succeeds, then later:
mkfifo(./work/pipe.a29154, _S_IFIFO | S_IRWXG | S_IRWXU)

which fails with errno 6

/usr/include/sys/errno.h
#define ENXIO 6
/* No such device or address */

As mentioned above, this code works on our older HP systems.

Any suggestions appreciated much!

Thanks in advance,

Tom

You shouldn't be passing in _S_IFIFO. That flag is used by by stat() and mknod(), but is not appropriate for mkfifo(). Perhaps the mkfifo function is actually checking for valid mode bits now.
