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

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.

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

NAME

       fstyp_strerror - get error message string

SYNOPSIS

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

       const char *fstyp_strerror(fstyp_handle_t handle, int error);

PARAMETERS

       handle	 Opaque handle returned by fstyp_init(3FSTYP). This argument is optional and can be 0.

       error	 Error value returned by a libfstyp function.

DESCRIPTION

       The  fstyp_strerror()  function	maps  the error value to an error message string and returns a pointer to that string. The returned string
       should not be overwritten.

       The following error values are defined:

       FSTYP_ERR_NO_MATCH	  No file system match.

       FSTYP_ERR_MULT_MATCH	  Multiple file system matches.

       FSTYP_ERR_HANDLE 	  Invalid handle.

       FSTYP_ERR_OFFSET 	  Supplied offset is invalid or unsupported by the module.

       FSTYP_ERR_NO_PARTITION	  Specified partition not found.

       FSTYP_ERR_NOP		  No such operation.

       FSTYP_ERR_DEV_OPEN	  Device cannot be opened.

       FSTYP_ERR_IO		  I/O error.

       FSTYP_ERR_NOMEM		  Out of memory.

       FSTYP_ERR_MOD_NOT_FOUND	  Requested file system module not found.

       FSTYP_ERR_MOD_DIR_OPEN	  Directory cannot be opened.

       FSTYP_ERR_MOD_OPEN	  Module cannot be opened.

       FSTYP_ERR_MOD_INVALID	  Invalid module version.

       FSTYP_ERR_NAME_TOO_LONG	  File system name length exceeds system limit.
