passing enum type as argument to import dpi-c function

mmk23
hi all, I'm passing an enum type to the formal arg for the import -DPI-C function as below. But I'm getting " unsupported datatype in formal argument." error while compiling with irun: 09.20-s011 code e.g typedef enum { OFF=0,ON=1 } POS_TYPE; import "DPI-C" function int my_wrpr ( input POS_TYPE p_type ); Please let me know what is the right way to pass the same. Thanks, mmk

    It seems that the compiler has not implemented support for passing enums directly to the C routine at this time. I believe that the following code will work:

      typedef enum { OFF=0,ON=1 } POS_TYPE;
      import "DPI-C" function int my_wrpr ( input int p_type ); 
      POS_TYPE p = ON;

      initial
      begin
        a = my_wrpr( p );
