fstyp_get_attr(3FSTYP)				 File System Type Identification Library Functions			    fstyp_get_attr(3FSTYP)

NAME
fstyp_get_attr - get file system attributes SYNOPSIS
cc [ flag... ] file... -lfstyp -lnvpair [ library... ] #include <libnvpair.h> #include <libfstyp.h> int fstyp_get_attr(fstyp_handle_t handle, nvlist_t **attrp); PARAMETERS
handle Opaque handle returned by fstyp_ident(3FSTYP). attrp Address to which the name-pair list is returned. DESCRIPTION
The fstyp_get_attr() function returns a name-value pair list of various attributes for an identified file system. This function can be called only after a successful call to fstyp_ident(). Each file system has its own set of attributes. The following attributes are generic and are returned when appropriate for a particular file system type: gen_clean (DATA_TYPE_BOOLEAN_VALUE) Attribute for which true and false values are allowed. A false value is returned if the file system is damaged or if the file system is not cleanly unmounted. In the latter case, fsck(1M) is required before the file system can be mounted. gen_guid (DATA_TYPE_STRING) Globally unique string identifier used to establish the identity of the file system. gen_version (DATA_TYPE_STRING) String that specifes the file system version. gen_volume_label (DATA_TYPE_STRING) Human-readable volume label string used to describe and/or identify the file system. Attribute names associated with specific file systems should not start with gen_. RETURN VALUES
The fstyp_get_attr() function returns 0 on success and an error value on failure. See fstyp_strerror(3FSTYP). ATTRIBUTES

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
fd 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. FILES
/usr/lib/fs/ Default module directory. /usr/lib/fs/fstype/fstyp.so.1 Default path to a libfstyp module for an fstype file system. ATTRIBUTES
