Не могу поймать fstat

Помогите, люди добрые: не могу поимать fstat. Ни как не могу найти ошибку:
[me]$ cat fakestat.c
/* fakestat.c*/
#include <sys/stat.h>
#define BUFFERLEN 256
int fstat (int fd, struct stat *statbuf);
int fstat (int fd, struct stat *statbuf){
return 10;
}
[me]$ cat stattest.c
#include <fcntl.h>
/*stattest.c*/
#include <sys/stat.h>
#include <errno.h>
#include <unistd.h>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <dlfcn.h>
int main(int argc, char *argv[])
{
char fileName[120];
struct stat statbuf, realstatbuf;
char timeBuf[50];
int a, statRet;

strcpy(fileName, "/etc/passwd");
a=open (fileName,O_RDONLY );
if (statRet=fstat(a, &statbuf)){
printf("could not fstat %s: %s\n", fileName, strerror(errno));
}
printf ("stat returned %d\n",statRet);
printf("passwd was accessed on %s\n",ctime(&statbuf.st_atime));
return 0;
}
