fstyp_init(3FSTYP) File System Type Identification Library Functions 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 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). ATTRIBUTES
