C# Prototype & Delegate in Compact Framework

[ThinkRS232]

I have a PocketPC .Net application (Compact Framework) that calls a Win32
DLL. This DLL in turn has a WINAPI type callback. Following is the actual
prototype.

Win32 DLL Function Prototype
-----------
Status = XferFiles(int PortID, int Direction, int Protocol, LPCTSTR Fspec,
int Flag, int (WINAPI *Callback)(int Chgflg, char *Fname, long Bytcnt, int
Curblk, int Errcnt, unsigned Rate));

1. What would the above C# function prototype look like?
2. And the delegate for the callback function?

Thanks

Hello, ThinkRS232!

TWin32 DLL Function Prototype
T-----------
TStatus = XferFiles(int PortID, int Direction, int Protocol, LPCTSTR
TFspec, int Flag, int (WINAPI *Callback)(int Chgflg, char *Fname, long
TBytcnt, int Curblk, int Errcnt, unsigned Rate));

T1. What would the above C# function prototype look like?
T2. And the delegate for the callback function?

What type returns XferFiels(...)?

C#
[DllImport("your.dll", SetLastError=true)]
XferFiles( int portID, int Direction, int Protocol, string Fspec, int Flag, CallbackDelegate callback);

delegate int CallbackDelegate(int Chgflg,
[MarshalAs(UnmanagedType.LPStr]
string Fname,
long Bytcnt,
int Curblk,
int Errcnt,
uint Rate);

Thanks for the reply. I am getting the error

"B:\CdrvCENet\CdrvCENet\CdrvCE.cs(778): The type or namespace name
'MarshalAs' could not be found (are you missing a using directive or an
assembly reference?)"

Is MarshalAs supported in the 1.x .Net Compact Framework? Otherwise, what
could be the error?

MarshalAs is supported only in CF 2.0.
For more info what is supported in CF 1.0 have a look at
