Passing a pointer to a struct

The book I have on this is completely useless (even it's examples don't work).

I am trying to pass a pointer to a structure to a function.

This is the structure:

Code:

---

struct cavestruct {
  int number;
  int door[3];
  bool visited;
} cave[200];

---

how would I pass this (either as a pointer or in its entirety) to another function?

ie. how would I change this (keeping the values already being passed)...

Code:

---

result=find_path(start_position, 79);

---

Maybe I should just leave it as a global variable...

P.S. To declare a pointer to an array of structures is it necessary to create an array of pointers or can I just declare one pointer to point at the address of the first element?

Thanks muchly...

This may not be 100% but should show you roughly how to go about this.

typedef struct
{
int iSize;
char sLocation[64];
}MY_STRUCT;


MY_STRUCT MyStruct[200];

//PROTOTYPE
int FindThat(MY_STRUCT **Data,int iIndex);

//CALL
iReturn=FindThat(&MyStruct,ArrayIndex);
(This should send the whole array)

//In FindThat() Function declare a pointer to use in locking down the array
MY_STRUCT *pData;
//Lock it to the pointer
pData=(MY_STRUCT*)*Data;

//use the array like
pData[iIndex]

struct cavestruct {
int number;
int door[3];
bool visited;
} cave;


typedef cave v;

then in ur main program u
int main () {

v *x;
x = (v *)malloc(200*sizeof(v));

Now u can pass this pointer to an function.
}

Now for cave[0]......................................cave[199] u could use the structure by incrementing the pointer.
