Marshaling for .Net Compact Framework

Mar 22 2007 5:34 PM

Sorry for precedent message, I don't see the to page error; I rewrie all.
I keep for other few tay this topic in this section; at the same time a move it in Compact Framework section.

Hi, I don't know is the right section for my question. Question: I must use C code in C# web services on PDA with PocketPC, but I have any problem with marshaling. Below I paste the C code and the C# code that I write (but it doesn't complete).

C code:

/* define Octet Length Type - normally int but could be short or long */

#define MR_P1363_OK 0

#define MR_P1363_DOMAIN_ERROR -1

#define MR_P1363_INVALID_PUBLIC_KEY -2

#define MR_P1363_INVALID -4

#define MR_P1363_DOMAIN_NOT_FOUND -5

#define MR_P1363_OUT_OF_MEMORY -6

#define MR_P1363_DIV_BY_ZERO -7

#define MR_P1363_BAD_ASSUMPTION -8
