What does that do?  Is it a system call?

There is NO compatibility between unix and MS-Windows.

Otherwise, perhaps you'll find a "compatibility layer" in wine...

I think what he meant to say was

Under Microsoft NT, the C function ntstatus() does <something>.
Is there an equivalent function under UNIX?
If not, how should I go	about doing <something>?

If I were a regular here, he would have been thoroughly berated for such
a badly written post.

No since in berating, he propbably doesn't use english as his native
language.  OTOH, he does need to tell us what ntstatus() does, since
nobody here is likely to admit familiarity.

A quick search through Google shows that NTSTATUS is the type of the
/return_code/ that MSWindows NT NTDLL kernel calls return to their
caller. A device driver (for instance) will call NT kernel functions to
perform certain operations, and receive a return code back. The return
code is akin to the POSIX/C userspace errno variable, in that it has
specific values for specific situations, no matter which function was
called. This return code is formatted as an NTSTATUS type, and can be
evaluated using one of several syscalls akin to the strerror() POSIX
userspace function.

So, if I read the OP correctly, he wants to know if the Unix kernel
functions (which Unix kernel is unspecified) provide a single, unified
return-code that can be evaluated to determine the result of the
function, no matter which kernel function was invoked.

To the OP: The answer is no. There is no equivalent to NTSTATUS in Unix,
since Unix is not a single implementation of an operating system, and
the internals of each implementation are different. /Some
implementations/ may provide an equivalent to NTSTATUS, however. Which
Unix are you interested in?

hi;
first i would like to say sorry for my poor english,and thanks a lot
for understanding my question. Thanks for such a nice reply;

is there any kernel function equivalent to NTSTATUS in linux;
linux kernel version is kernel-2.6.5-1.358 on i686,
if, there is nothig with the similar functionality in linux as
NTSTATUS,how can i achieve such a unified return-code or such
functionality.

thanks and plz excuse for such english;

thanks a lot;

srinivas.

Errrm, what does NTSTATUS do?

Check the "NTSTATUS Relevance" parallel thread.

Apparently, you haven't gotten Lew Pitcher's post to this thread yet.

NTSTATUS is to the WIN NT kernelspace what errno is to the POSIX
userland: It's (the type of) a single variable used to report errors
raised by various and divers syscalls.
