sam_restore_copy(3)

NAME
     sam_restore_copy - Creates an archive copy for a Sun QFS or
     SAM-QFS file

SYNOPSIS
     cc [ flag ... ] file ...  -L/opt/SUNWsamfs/lib
     -lsam [ library ... ]

     #include "/opt/SUNWsamfs/include/stat.h"

     int sam_restore_copy(const char *path, int copy, struct
     sam_stat *buf, size_t bufsize, struct sam_section *vbuf,
     size_t vbufsize);

DESCRIPTION
     The sam_restore_copy() library routine creates an archive
     copy for an existing Sun QFS or SAM-QFS file.  The file must
     already exist and the archive copy must not exist.  The
     sam_restore_copy() library routine creates an archive copy
     using information supplied by the user and obtained from a
     source such as the archiver.log.  This library routine
     accepts the following arguments:

     path      The path name to the file where the archive copy
               is being created.  It may be an absolute or
               relative path name, but it must be no longer than
               PATH_MAX (see the /usr/include/limits.h file).

     copy      The copy number (0, 1, 2, or 3) of the archive
               copy that is being created.

     buf       A sam_stat structure.  See sam_stat(3).

     bufsize   The size of the sam_stat structure.  See
               sam_stat(3).

     vbuf      A sam_section structure for the array of VSNs if
               the archive copy overflowed volumes, that is,
               n_vsns > 1.  If n_vsns = 1, vbuf should be set to
               NULL.  See sam_stat(3).

     vbufsize  The size of the sam_section structure.  If n_vsns
               = 1, vbufsize should be set to 0.  See
               sam_stat(3).

     The following members in the sam_stat structure must exist.
     All other fields are ignored.

     ulong_t      st_mode      /* File mode (see mknod(2)) */
     ulong_t      st_uid       /* User ID of the file's owner */
     ulong_t      st_gid       /* Group ID of the file's owner */
     u_longlong_t st_size      /* File size in bytes */

     ulong_t      st_atime     /* Time of last access      */
     ulong_t      st_ctime     /* Time of last file status change */
     ulong_t      st_mtime     /* Time of last data modification  */

     The following members in the sam_copy_s structure must exist
     for the copy.  All other fields are ignored.

     u_longlong_t position;    /* Position of the file on the media. */
     time_t       creation_time; /* Time the archive copy was created */
     uint_t       offset;      /* Location of the copy in the archive file */
     short        n_vsns;      /* Number of volumes used by the archive */
     char         media[4];    /* Two character media type. */
     char         vsn[32];     /* Volume serial name of the media volume */

     The preceding fields have the following meaning:

     position  The position of the file recorded on the media.

     creation_time
               This is the time that the archive was made.  If
               creation_time is zero, it is set to the value of
               time().

     offset    The location of the copy in the archive file in
               units of 512 bytes.

     n_vsns    The number of volumes that this copy spans.

     vsn       The volume serial name of the cartridge where the
               file resides.

     media     The two-character media type.  For example, the
               media type for DLT tape is lt.  See mcf(4).

RETURN VALUES
     Upon succesful creation of a file, a value of 0 is returned.
     Otherwise, a negative value is returned and errno is set to
     indicate the error.  The possible return values are:
     -1    user is not root
     -2    invalid copy number
     -3    invalid VSN
     -4    file does not exist
     -5    file open failed
     -6    uid and gid do not match those for the existing file
     -7    invalid VSN for this copy
     -8    multiple copies but vbufsize incorrect
     -9    media type invalid
     -10   copy restore failed for some other reason

FILES
     /etc/opt/SUNWsamfs/mcf
                         The configuration file for Sun QFS or

                         SAM-QFS file systems.
