/* * This is a native test to explore how the readdir() family works. * Newlib supports the following readdir() family members: * * closedir() - * readdir() - * scandir() - * opendir() - * rewinddir() - * telldir() - BSD not in POSIX * seekdir() - BSD not in POSIX * * * seekdir() takes an offset which is a byte offset. The Linux * implementation of this appears to seek to the ((off/DIRENT_SIZE) + 1) * record where DIRENT_SIZE seems to be 12 bytes. * * * * $Id: test.c,v 1.2 2001-09-27 12:02:26 chris Exp $ */ #include <stdio.h> #include <sys/types.h> #include <fcntl.h> #include <dirent.h> #include <string.h> #include <assert.h> #include <unistd.h> #include <errno.h> DIR *directory;
