If you can compile your C code into a dll, then I recommend that you use
a Call Library Function (CLF) instead of a CIN. The amount of steps that
you need to follow to make a CIN work can become frustrating. With a CLF,
you need only make a function prototype, and you're done! The main advantage
that a CIN gives is that you have the ability to resize the dataspace a variable
has inside the code. For example, if you pass an a
rray of 100 DBLs out of
LabVIEW (into your C code)and try to pass 150 DBLs back into LabVIEW (from
your C code)then bad things will happen. There exists CIN tools that allow
you to resize the dataspace, so that LabVIEW will allocate a larger buffer
for the return data, and no errors will occur. If you are not resize dataspaces,
then don't worry. If you are, then just include the labview.lib library
in the LabVIEW/cintools/win32 directory.
For more information on calling dlls, look at this article: http://ni.com/support/labview/program/callcode/callmain.htm
