 Sample code which searches a directory for entry ``name'' is:
 .Bd -literal -offset indent
-len = strlen(name);
 dirp = opendir(".");
 if (dirp == NULL)
 	return (ERROR);
+len = strlen(name);
 while ((dp = readdir(dirp)) != NULL) {
 	if (dp->d_namlen == len && strcmp(dp->d_name, name) == 0) {
 		(void)closedir(dirp);
