NAME sam_unrearch - Removes rearchive attributes on a file or directory SYNOPSIS cc [ flag ... ] file ... -L/opt/SUNWsamfs/lib -lsam [library ... ] #include "/opt/SUNWsamfs/include/lib.h" int sam_unrearch(const char *path, int num_opts, ... ); DESCRIPTION sam_unrearch() lets you remove a request to rearchive a file or a directory using a Sun Storage Archive Manager system call. path is the file on which to remove the attributes, followed by a sequence of num_opts input characters or options. Individual options are described below. For example, if you have used the sam_rearch(3) function to request that a file be rearchived, you can use the sam_unrearch function to clear the bit that the sam_rearch(3) function had set. The specifications for the archive copy (c copy_no) and/or the media type and VSN (m media_type [v vsn]) determine which archive copy is affected. There are several ways to remove the request to rearchive from one or more archive entries. These ways are as fol- lows: o By copy number o By copy number, media type, and VSN o By copy number and media type o By media type o By media type and VSN OPTIONS c copy_no Removes the rearchive request for copy_no. Specify 1, 2, 3, or 4 for copy_no. If one or more 'c' options are are specified, the function removes the rearchive request from only those archive copies (1, 2, 3, or 4). Either a "c copy_no" or a "m media" option must be specified. M Removes rearchive requests for metadata only. This includes directories, the segment index, and removable media files. Regular files and symbolic links are not unrearchived. If you are unarchiving a directory, you must specify the "M" option. m media Removes rearchive requests from all archive copies on the specified media_type. For the list of possible media_type specifications, see the mcf(4) man page. Either a "c copy_no" or a "m media" option must be specified. If you specify a "m media" option, you can also specify a "v vsn" option. v vsn Removes the rearchive requests for the archive copies on vsn. For vsn, specify a volume serial name (VSN). If you specify a "v vsn" option, you must also specify a "m media" option. RETURN VALUES Upon successful completion a value of 0 is returned. Other- wise, a value of -1 is returned and errno is set to indicate the error. ERRORS sam_unrearch() 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 superuser. EFAULT Argument points to an illegal address. EINTR A signal was caught during the sam_unrearch() 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 com- ponent 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. SEE ALSO unrearch(1m), rearch(1m), sam_rearch(3), mcf(4)
