LVBoolean passed to cvi fail.

Hi all,

   i had created a dll  from a labview code, the Header of the dll is:

  void __cdecl Validation(Enum num, DO Enum, Enum1 Channel, LVBoolean *Etat,  LVBoolean *Etat2);

  but LVBoolean is not supported in cvi, the how to proceed to pass boolean values?

  Regards,

SASA
