how to print the contetnt of one directory?

Hi Experts,

How can I write a program in C which takes the path to the directory as an input, and prints the files, and directories inside that directory, like ls?

Hi zahmadian,

  Use the findfirst() or opendir() function to initiate reading of a directory, then use findnext() or readdir() to continue.

Good Luck!

suppose I am using readdir in while loop, then what is the condition to stop reading...
You'd do that like

#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>

int main(int argc, char **argv)
 DIR *dir = opendir(".");
 struct dirent *entry;
 while((entry = readdir(dir)) != NULL)
   printf( "Entry filename is: %s\n", entry->d_name);

 return 0;

'readdir()' returns NULL when there are no more files in the directory.
