NAME
       fstyp_init, fstyp_fini - initialize and finalize libfstyp handle

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

       int fstyp_init(int fd, off64_t **offset, char *module_dir,
	    fstyp_handle_t *handle);

       void fstyp_fini(void *handle);

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.

       module_dir    Optional location of the libfstyp modules.

       handle	     Opaque handle to be used with libfstyp functions.

DESCRIPTION
       The  fstyp_init()  function  returns  a handle associated with the specified parameters. This handle should be used with all other libfstyp
       functions.

       If module_dir is NULL, fstyp_init() looks for modules in the  default  location:  /usr/lib/fs  subdirectories.  The  fstyp_init()  function
       locates libfstyp modules, but might defer loading the modules until the subsequent fstyp_ident() call.

       If  module_dir  is  other  than NULL, the fstyp_init() function locates a module in the directory that is specified. If no module is found,
       fstyp_init fails with FSTYP_ERR_MOD_NOT_FOUND.

       Modules that do not support non-zero offset can fail fstyp_init() with FSTYP_ERR_OFFSET.

       The fstyp_fini() function releases all resources associated with a handle and invalidates the handle.

RETURN VALUES
       The fstyp_init() function returns 0 on success and an error value on failure. See fstyp_strerror(3FSTYP).
