Here's a simple program that prints the names of the files in the current working directory:
#include <stddef.h> #include <stdio.h> #include <sys/types.h> #include <dirent.h> int main (void) { DIR *dp; struct dirent *ep; dp = opendir ("./"); if (dp != NULL) { while (ep = readdir (dp)) puts (ep->d_name); (void) closedir (dp); } else puts ("Couldn't open the directory."); return 0; }
The order in which files appear in a directory tends to be fairly random. A more useful program would sort the entries (perhaps by alphabetizing them) before printing them; see section Scanning the Content of a Directory, and section Array Sort Function.
Go to the first, previous, next, last section, table of contents.
