GNU Info (libc.info)Simple Directory Lister Mark IISimple Program to List a Directory, Mark II ------------------------------------------- Here is a revised version of the directory lister found above (Note: Simple Directory Lister). Using the `scandir' function we can avoid the functions which work directly with the directory contents. After the call the returned entries are available for direct use. #include <stdio.h> #include <dirent.h> static int one (struct dirent *unused) { return 1; } int main (void) { struct dirent **eps; int n; n = scandir ("./", &eps, one, alphasort); if (n >= 0) { int cnt; for (cnt = 0; cnt < n; ++cnt) puts (eps[cnt]->d_name); } else perror ("Couldn't open the directory"); return 0; } Note the simple selector function in this example. Since we want to see all directory entries we always return `1'. automatically generated by info2www version 1.2.2.9 |
