Help, input from a file

Iam trying to count the frequency of words read from a file, but when l try to run the program it just hungs up does nothing, lam relatively new in this field. My code is as shown bellow, what lam l not doing right?


#include <stdio.h>
#include <ctype.h>
#include <string.h>
#include <stdlib.h>

#define MAXWORD 1000


struct tnode {
char *word;
int count;
struct tnode *left;
struct tnode *right;
};

struct tnode *addtree(struct tnode *, char *);
void treeprint(struct tnode *);
struct tnode *talloc(void);
int getword(char *, int);
char *strdupl(char *);


/* word frequency count */

int main(void)
{
struct tnode *root;
char word[MAXWORD];
root = NULL;

while (getword(word, MAXWORD) != EOF)
if (isprint(word[0]))
root = addtree(root, word);
treeprint(root);
exit (0);
}

/* addtree: add a node with w, at or below p */

struct tnode *addtree(struct tnode *p, char *w)
{
int cond;

if (p == NULL) { /* a new word has arrived */
p = talloc(); /* make a new node */
p->word = strdupl(w);
p->count = 1;
p->left = p->right = NULL;
}

else if ((cond = strcmp(w, p->word)) == 0)
(p->count)++; /* repeated word */
else if (cond < 0) /* less than into left subtree */
p->left = addtree(p->left,w);
else /* greater than into right subtree */
p->right = addtree(p->right,w);
return p;
}

/* treeprint: in-order print of tree p */

void treeprint(struct tnode *p)
{
if (p !=NULL) {
treeprint(p->left);
printf("%4d %s\n", p->count, p->word);
treeprint(p->right);
}
}


/* talloc: make a tnode */

struct tnode *talloc(void)
{
return (struct tnode *) malloc(sizeof(struct tnode));
}


/* getword: get next word or character from input */

int getword(char *word, int lim)
{

FILE *pFile;
int c;
char *w = word;

pFile = fopen ("/mnt/samba/k/patrick/testp.txt","r");

while (isspace(c = fgetc(pFile)))
;
if (c != EOF)
*w++ = tolower(c);
if (!isprint(c)) {
*w = '\0';
return c;
}
for ( ; --lim > 0; w++)
if(!isalnum(*w = fgetc(pFile)) && !ispunct(*w)) {
ungetc(*w,pFile);
break;
}

*w = '\0';
fclose(pFile);
return word[0];
}

/* strdupl: make duplicate of s. (strdup builtin) */

char *strdupl(char *s)
{
char *p;
p = (char *) malloc(strlen(s)+1);
if (p != NULL)
strcpy(p, s);
return p;
}
