I was hoping to get some assistance with this C program I am working on. The goal is to find the largest file in the current directory and then display this filename along with the filesize. What I have so far will display all the files in the current directory. But, how do I deal with "grabbing" and displaying the filesize?

So far:

CODE

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

void printfile(char *dir)
{
DIR *dp;
struct dirent *entry;
struct stat statbuf;

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

}

chdir(dir);
while((entry = readdir(dp)) != NULL) {

lstat(entry->d_name, &statbuf);

if(S_ISREG(statbuf.st_mode)) {
printf("%s\n", entry->d_name);
}

}
closedir(dp);
}

int main()
{
printfile(".");
exit(0);
}

Shouldn't something like this work for filesize? It doesn't print the correct size.

CODE

struct stat statbuffer;
struct dirent *entry;
if(S_ISREG(statbuffer.st_size){
int i = sizeof(entry->d_name);
printf("%d\n", i);}

Any help would be greatly appreciated.
