Convert labview VI to C code

Question

Hi,
I've to translate LabvIEW code to C code (CVI). Does any exist?
Thank you in advance.

Thanks for your answer,
The purpose is to adapt drivers, tested via LabVIEW, into C in order
to load it in our device (real time). So we're close of the
hardware and we must have a "light" code.
Concerning the use of a dll or of an exe, don't we need to install
the LV runtime engine (heavy) and all associates runtimes to get it
running? If true, the installation and use of the program should take
more place and time than using a simple C executable?
I still have a few misunderstanding concerning the portability of LabVIEW code, even in exe or dll...
As
Dennis already has pointed out: The only sort of LabVIEW to C converter
is part of the LabVIEW embedded system. It's C code however is only
supporting a subset of LabVIEW (no IO libraries and some of the more
advanced internal nodes) and not really meant to be used as a C code
for further use outside of LabVIEW embedded. It's readibility as normal
C code is quite hairy eventhough it is syntactically C.
In fact it won't even compile on other systems easily as LabVIEW
embedded comes with quite some specific runtime support to connect to
the compiled code on the target system and do quite a lot of other
things too, which all get built into the executable as well and which
all will be used directly or indirectly by the created C code.
CVI has a runtime too, and I'm not sure what you mean with all its associated other runtimes.
LabVIEW code in source code is generally portable across all LabVIEW
platforms of the same version and also into newer versions. LabVIEW
executables are only portable inside the family of system they were
created for. This family is both a combination of OS and CPU. So
LabVIEW created for Windows will run on all supported Windows platforms
(the newest version only supports 2000/XP/2003 anymore) but not on
Linux, MacOSX or an RT system.
An executable for MacOSX will only run on MacOSX but I think on most of
their versions although there have been specific issues with certain OS
versions. If you happen to have an Intel Mac it would only run on a
dual boot system with XP on it too, or in the emulation environment
called Rosetta if they didn't rename that in the meantime.
Basically if the OS type changes or the CPU, you can't use an
executable anymore other than in certain emulation environments that
provide the old environment.
