Programming

Hi
i need C code to list direcoty without using ls command and it sould take the path of the directory from the user?

"please help me it is so important"

#include <stdio.h>
#include <string.h> // for access
#include <fcntl.h>
#include <dirent.h> // for struct dirent
#include <sys/stat.h> //for struct stat and the functions related to it

int main(int argc, char **argv)
{
struct dirent *dp;
DIR *dirp; // structure for the directory

if(argc != 2) {
fprintf(stderr, "Usage: ./a.out dirName");
exit(1);
}

dirp=opendir(argv[1]);
while((dp=readdir(dirp))!= NULL)
printf("%s\n", dp->d_name);
}

thanx for your help but i need that with out using C function also
like "printf(),opendir()", it must use system calls only like "read(),write"

The artificial restriction tells us that this is a homework assignment. If you read the unix.com rules:

... you'll see that homework assignments do not belong here, so I'll close the thread. Tell your teacher what you're having problems with and I'm sure he'll help you out.
