FSTYP_INIT(3FSTYP)FSTYP_INIT(3FSTYP)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 con‐
tains 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 speci‐
fied 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 subse‐
quent 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 han‐
dle and invalidates the handle.
RETURN VALUES
The fstyp_init() function returns 0 on success and an error value on
failure. See fstyp_strerror(3FSTYP).
