NAME

fstyp_mod_init, fstyp_mod_fini, fstyp_mod_ident, fstyp_mod_get_attr, fstyp_mod_dump - libfstyp module interface

SYNOPSIS

cc [ flag... ] file... -lfstyp  -lnvpair  [ library... ]
#include <libnvpair.h>
#include <libfstyp.h>

int fstyp_mod_init(int fd, off64_t **offset, fstyp_mod_handle_t *handle);

void fstyp_mod_fini(fstyp_mod_handle_t handle);

int fstyp_mod_ident(fstyp_mod_handle_t handle);

int fstyp_mod_get_attr(fstyp_mod_handle_t handle, nvlist_t **attr);

int fstyp_mod_dump(fstyp_mod_handle_t handle, FILE *fout, FILE *ferr);

PARAMETERS

: Open file descriptor of a block or a raw device that contains the file system to be identified.

offset

: Offset from the beginning of the device where the file system is located.

handle

: Opaque handle that the module returns in fstyp_mod_init() and is used with other module functions.

fout

: Output stream.

ferr

: Error stream.

DESCRIPTION

A libfstyp module implements heuristics required to identify a file system type. The modules are shared objects loaded by libfstyp. The libfstyp modules are located in /usr/lib/fs subdirectories. A subdirectory name defines the name of the file system.

Each module exports the fstyp_mod_init(), fstyp_mod_fini(), fstyp_mod_ident(), and fstyp_mod_get_attr() functions. All of these functions map directly to the respective libfstyp interfaces.

The fstyp_mod_dump() function is optional. It can be used to output unformatted information about the file system. This function is used by the fstyp(1M) command when the -v option is specified. The fstyp_mod_dump() function is not recommended and should be used only in legacy modules.
