TinyDir

Lightweight, portable and easy to integrate C directory and file reader. TinyDir wraps dirent for POSIX and FindFirstFile for Windows.

Windows unicode is supported by defining UNICODE and _UNICODE before including tinydir.h.

Example

There are two methods. Error checking omitted:

tinydir_dir dir;
tinydir_open(&dir, "/path/to/dir");

while (dir.has_next)
{
	tinydir_file file;
	tinydir_readfile(&dir, &file);

	printf("%s", file.name);
	if (file.is_dir)
	{
		printf("/");
	}
	printf("\n");

	tinydir_next(&dir);
}

tinydir_close(&dir);

tinydir_dir dir;
int i;
tinydir_open_sorted(&dir, "/path/to/dir");

for (i = 0; i < dir.n_files; i++)
{
	tinydir_file file;
	tinydir_readfile_n(&dir, &file, i);

	printf("%s", file.name);
	if (file.is_dir)
	{
		printf("/");
	}
	printf("\n");
}

tinydir_close(&dir);

See the /samples folder for more examples, including an interactive command-line directory navigator.
