Xenroll.h Error

[pknight12133123123]

I am trying to implement getting X.509 Certificates from a CA using LabWindows or LabView.  I started using LabWindows as most sample programs on the newt are in C .  However when I include the xenroll.h from c:\program files\national instruments\cvi85\sdk\include and the uuid.lib from  c:\program files\national instruments\cvi85\sdk\lib.

At this line of the xenroll.h file    

extern "C" IEnroll * WINAPI PIEnrollGetNoCOM(void);

I get the following errors:

 csi.c - 3 errors, 1 warning
  "Xenroll.h"(5608,8)   Warning: Empty declaration.
  "Xenroll.h"(5608,8)   syntax error; found 'string constant' expecting ';'.
  "Xenroll.h"(5608,8)   Unrecognized declaration.
  "Xenroll.h"(5608,20)   Redeclaration of 'IEnroll' previously declared at Xenroll.h:62.

This file comes directly from NI, why is there an error and how do I fix it?

Thanks

This header apparently was not modified properly to allow it to be used by a C compiler. The extern "C" syntax is not supported by the CVI compiler. Apparently this library doesn't see much use; this header has included those extern "C" declarations at least since 1999, and no one has pointed this out before. You should replace extern "C" with EXTERN_C, which is used thoughout the rest of that file. Sorry again.
