Header files

The following header files contain useful things for filesystem handlers:

<devctl.h> — contains the definition for devctl(), and also defines the component flags used to create a command.
<dirent.h> — contains the directory structure type used by readdir().
<sys/dcmd_blk.h> — contains the DCMD_FSYS_* devctl() block commands (see the Devctl and Ioctl Commands reference).
<sys/disk.h> — defines partition_entry_t.
<sys/dispatch.h>, <sys/iofunc.h> — Used by resource managers.
<sys/fs_stats.h> — defines the fs_stats structure returned by the FSYS block command DCMD_FSYS_STATISTICS.
<sys/mount.h> — defines the mount flags.
<tar.h> — defines the layout of the .tar header.
<zlib.h> — contains the definitions for the transparent compression library.
