Counting the number of files in a directory using C

Question

How can I count the number of files in a directory using C on linux platform.

Answer 1

No guarantee that this code compiles, and it's really only compatible with Linux and the BSDs:

#include <dirent.h>  ...  int file_count = 0; DIR * dirp; struct dirent * entry;  dirp = opendir("path"); /* There should be error handling after this */ while ((entry = readdir(dirp)) != NULL) {     if (entry->d_type == DT_REG) { /* If the entry is a regular file */          file_count++;     } } closedir(dirp);
