sam_archive(3)

NAME
sam_archive - Sets archive attributes on a file or directory

SYNOPSIS

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

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

int sam_archive(const char *path, const char *ops);

DESCRIPTION

sam_archive() sets archive attributes on a file or directory using a Sun StorageTek SAM-FS or Sun SAM-QFS system call. path is the file on which to set the attributes. ops is the character string of options, for example: "dn". Individual options are described below.

OPTIONS

C   Specifies concurrent archiving for this file. This file can be archived even if opened for write. The archive time is regulated by the modification time. Note, nfs files are not opened and are by default concurrently archived. Concurrent archiving is useful for databases, however caution is advised since archiving can occur while the file is being modified and this can result in wasted media. The default is to disallow archiving while the file is opened for write.

I   Support inconsistent archive copies. This means that an archive copy can be created even if the file is modified while it is being copied to the media. By default, the archive copy is disallowed if the file is inconsistent, that is, if the file is modified while it was being copied to the media. Note, the file cannot be staged if the copy is marked inconsistent; however, after a samfsrestore, the inconsistent flag is removed from the archive copy and the file can be staged.

    Inconsistent archiving is useful for databases, however caution is advised because it a file can be staged from an inconsistent copy after the file is restored using samfsrestore.

d   Return the archive attributes on the file to the default, i.e. archive the file according to the archiver rules. When this option is specified, the attributes are reset to the default. If it is used, it should be the first character in the string.

i   Specifies that the file be immediately archived if it is not already archived.

w   Wait for the file to have at least 1 archive copy before completing. Not valid with d or n.

    Note that it may take a long time for the file to be archived.

W   Wait for the file to have all its required archive copies before completing. Not valid with d or n.

    Note that it may take a long time for the file to be archived.

n   Specifies that this file never be archived. Not valid with either of the checksum g (generate) or u (use) attributes. (See ssum(1) or sam_ssum(3)).

RETURN VALUES
Upon successful completion a value of 0 is returned. Otherwise, a value of -1 is returned and errno is set to indicate the error.

ERRORS

sam_archive() fails if one or more of the following are true:

EINVAL
    An invalid option was specified, or the file is neither a regular file nor a directory.

EPERM
    Not the owner or super-user.

EFAULT
    path or ops points to an illegal address.

EINTR
    A signal was caught during the sam_archive() function.

ELOOP
    Too many symbolic links were encountered in translating path.

ENAMETOOLONG
    The length of the path argument exceeds {PATH_MAX}, or the length of a path component exceeds {NAME_MAX} while {_POSIX_NO_TRUNC} is in effect.

ENOENT
    The named file does not exist or is the null pathname.

ENOLINK
    path points to a remote machine and the link to that machine is no longer active.

ENOTDIR
    A component of the path prefix is not a directory.
