Calling a dll function that as a structure

Question

I'm trying to call the following function with the Call library function node:
XLstatus xlLinSetChannelParams (
XLportHandle portHandle,
XLaccess accessMask,
XLlinStatPar statPar)
The statPar parameter is a stucture which is define as follow
typedef struct {
unsigned int LINMode
int baud rate;
unsigned int LINVersion;
unsigned int reserved;
} XLlinStatPar;
I used a cluster to pass the data to the function but labview is crashing everytime. The  C output of the CLFN is :
typedef struct {
 unsigned long LinMode;
 long baudrate;
 unsigned long Linversion;
 unsigned long reserved;
 } TD1;
long _xlLinSetChannelParams28(long portHandle, uInt64 accessMask,
 TD1 *statPar);
Why is labview sending a pointer to the struct instead of the structure itself? Is this the cause of my problem? Any Solution?

The CLFN ouput shown in my previous message was done with the "handle to value" parameter. As you stated, it sends a reference to the struct memory location.The problem is that i need to pass the structure value as an input and not a pointer to it (well, that's what i think the problem is). I read the various documents about CLFN and I tried the examples but they are all have function of that kind:
returnval ExampleFunc (structPointer *struct)
While the function in my dll is made like that
returnval ExampleFunc (structValue struct) (see the real function in my first message)
I included the dll and Vi and documentation for the xlLinSetChannelParams function.  The CLFN node that calls it is the fourth one (the one with a cluster as input). The first 3 CLFN are used to call the initialization function:init driver,get channel and open port.
