c question

Hi group,

I have constructed the following code:

-----------------------------------------------------------------------------------------------------------------------------

#include "TreeElement.h"

struct node
{ TreeElementType elt;
struct node *left, *right;
};
typedef struct node Node;

typedef Node *Tree;

/* Tree Type. */

----------------------------------------------------------------------------------------------------------------------------

typedef char TreeElementType[11];

#define TreeElementLess(e1, e2) (strcmp(e1,e2) < 0)
/* i.e. e1 < e2 */

#define TreeElementMove(e1, e2) (strncpy(*e2, e1, 10))
/* i.e. e2=e1 */

/* Define Tree of Short Alphanumeric Strings */

---------------------------------------------------------------------------------------------------------------------------

#include <stdio.h>
#include "tree.h"

void WriteTreeSlave( Tree T, int indent ) /*L.Allison*/
/* Write a tree, with root at the LHS, by a right-to-left, infix traversal */
{ int i; char str[]="----------|";

if( T != NULL )
{ WriteTreeSlave(T->right, indent+1);

      for(i=0; i < indent; i++) printf("          |");
      sprintf(str, "%s", T->elt);      /* NB. assumed to be a Tree of String */
      i = 0;
      while( str[i] != NULL ) i++;
      while( i < 10 ) { str[i]='-'; i++; }
      str[i] = '|'; str[i+1] = NULL;
      printf("%s\n", str);

WriteTreeSlave(T->left, indent+1);
}
}/*WriteTreeSlave*/

void WriteTree( Tree T ) { WriteTreeSlave(T, 0); }

/* Write a Tree down the page. */

int main (){
WriteTreeSlave("paul",0);
}
---------------------------------------------------------------------------------------------------------------------------------------------------------------------

It is my goal to call the function "WriteTreeSlave(?,?)" but I don't know what variables I have to give along with this function (that's why I placed the ?-mark there) . Ik have tried ("paul",0); but that doesn´t work. Can anybody help me?

Thanks in advance,

Paul Akkermans
