get the file directory

[Shiang Chin]

I am trying to the file list of a file directory on
Sun station running Unix. Can someone read the following
C code for me; I don't know what's wrong on my code.

#include <stdio.h>
#include <sys/types.h>
#include <sys/dir.h>
main(){
dir(".");
exit(0);
}

int dir(path)
  char* path;
{
  int fd;
  struct direct nbuf;

	if ((fd = open(path,0)) == -1)
  		return (0);
	while (read(fd,&nbuf, DIRSIZ(&nbuf)) {
		if (nbuf.d_fileno != 0)
			printf("%u %s\n",nbuf.d_namlen,nbuf.d_name);
		else 
			printf("error\n");
	}
	return 1;
}

If anyone knows the problem, please tell me how to solve this.
Thanks a lot.
