Hi everybody. I am working with Eicon's X.25 Development tools. The
tools come with a "Ex25.dll" that I need to interact with, from my C#
code. I have been marginally succesfull in getting some of the method
calls to work. For example:
the Ex25.dll has this:
OSEXTERN OSINT OSFNDEF x25init(message,uMsg)
OSINT message; /* message flag for request completion */
unsigned int uMsg; /* Identifies message if using messaging */
and in C# I can call it by doing this:
[DllImport("Ex25.dll")]
public static extern int x25init(int message, int uMsg);
So far so good.
There is also a struct:
struct x25doneinfo
{
OSINT xi_len; /* xi_buf length in bytes */
char OSSDTPTR xi_buf; /* Buffer address */
OSINT xi_cid; /* Connection id */
OSINT xi_cmd; /* Command code */
OSINT xi_info; /* X-bit field */
OSINT xi_retcode; /* Return code */
void *xi_ref; /* user reference pointer */
};
whose C# equivalent is (I think):
struct x25doneinfo
{
int xi_len;
[MarshalAs(UnmanagedType.LPStr)] public string xi_buf;
int xi_cid;
int xi_cmd;
int xi_info;
int xi_retcode;
[MarshalAs(UnmanagedType.AsAny)] object xi_ref;
};
The problem I am having come here, when in the ".h" file, they have
this:
/* Null post routine */
#define X25NULLFN (void (OSFNPTR)(struct x25doneinfo *))0 /*
NULL function pointer */
I have no idea how to "convert" this to a C# equivalent. Any help /
tips / pointers that anyone could give me on this would be greatly
appreciated.
Thanks in advance,
Hemant
