Hi, I have a Struct in C defined like this:

typedef struct _xmySTRUCT
   {

   char   chSomeChar;
   <...>
   double dProperty[ 10];
   double dProptype[ 10];
   char   szPropname[ 10][  21];
   <...>
   } xmySTRUCT, *PxmySTRUCT;


In Python I defined the struct like this:
class MyStructPy(Structure):
   _fields_ = [   ("somechar"           , c_char                          )
                , ("property"           , c_double                  *  10 )
                , ("proptype"           , c_double                  *  10 )
                , ("propname"           , c_char * 21               *  10 )
]


I let my C-Applicatino load Data in the struct and then I try to read out the values in Python.
When I try to access the array of doubles, I get some incorrect values (e.g.
0.000000
0.000000
0.000000
0.000000
0.000000
0.000000
2705755772498316500000000000000000000000.000000
2706128776157293300000000000000000000000.000000
2705755777574079800000000000000000000000.000000
0.000000

And strangely the Values in Char-Array all seem to miss the first character.
Thats why I think the problem has something to do with pointers?

I have several such structs in C without Arrays of doubles or Char-Arrays and they work fine, but these arrays make problems.
Can somebody point me in the direction, what I do wrong?

Thank you,
Mathias
