[c-prog] this code won't compile

[KBill]

Hello,

I'm very new to programming so I have a harder time debugging than most.
I have conflicting types of a function here, which is why this code
won't compile, yet I don't know as to whether or not this is the legal
way to do it. Here's the code: BTW, it came straight from a book.

#include <unistd.h>
#include <stdio.h>
#include <dirent.h>
#include <string.h>
#include <sys/stat.h>
#include <stdlib.h>

int main()
{
        printf("Directory scan of /home/omicron722:\n");
        printdir("/home/omicron722",0);
        printf("done.\n");

        exit(0);
}

void printdir(char *dir, int depth)
{
        DIR *dp;
        struct dirent *entry;
        struct stat statbuf;

        if((dp = opendir(dir)) == NULL) {
                fprintf(stderr, "cannot oepn directory: %s\n", dir);
                return;
        }

        chdir(dir);
        while((entry = readdir(dp)) != NULL) {
                lstat (entry->d_name,&statbuf);
                if(S_ISDIR(statbuf.st_mode)) {
                        /* found a directory, but ignore . and .. */
                        if(strcmp(".",entry->d_name) == 0 ||
                                strcmp("..",entry->d_name) == 0)
                                continue;
                        printf("%*s%s/\n",depth,"",entry->d_name);
                        /* Recurse at new indent level */
                        printdir(entry->d_name,depth+4);
                }
                else printf("%*s%s\n",depth,"",entry->d_name);
        }

        chdir("..");
        closedir(dp);
        }


This is supposed to just list my home directory contents. Any help
much appreciated.
