RFIO_CHOWN(3)						      Rfio Library Functions						     RFIO_CHOWN(3)

NAME

       rfio_chown - change owner and group of a directory/file

SYNOPSIS

       #include <sys/types.h>
       #include "rfio_api.h"

       int rfio_chown (const char *path, uid_t new_uid, gid_t new_gid)

DESCRIPTION

       rfio_chown  sets  the  owner and the group of a directory/file to the numeric values in owner and group respectively.  If owner or group is
       specified as -1, rfio_chown() does not change the corresponding ID of the file.

       path   specifies the logical pathname relative to the current directory or the full pathname.

       The effective user ID of the process must match the owner of the file or be super-user.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       EPERM	    The effective user ID does not match the owner of the file and is not super-user.

       ENOENT	    The named file/directory does not exist or is a null pathname.

       EACCES	    Search permission is denied on a component of the path prefix or write permission on the file itself is denied.

       EFAULT	    path is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       EINVAL	    new_uid or new_gid is invalid.

       ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SETIMEDOUT   Timed out.

       SECONNDROP   Connection closed by remote end.

       SECOMERR     Communication error.

NAME

       dpns_chown - change owner and group of a DPNS directory/file in the name server

SYNOPSIS

       #include <sys/types.h>
       #include "dpns_api.h"

       int dpns_chown (const char *path, uid_t new_uid, gid_t new_gid)

       int dpns_lchown (const char *path, uid_t new_uid, gid_t new_gid)

DESCRIPTION

       dpns_chown  sets the owner and the group of a DPNS directory/file in the name server to the numeric values in owner and group respectively.
       If owner or group is specified as -1, dpns_chown() does not change the corresponding ID of the file.

       dpns_lchown is identical to dpns_chown except for symbolic links: it does not follow the link but changes the ownership of the link itself.

       path   specifies the logical pathname relative to the current DPNS directory or the full DPNS pathname.

       To change the owner ID, if the group ID does not change and if the caller and the new owner ID belong to that group, GRP_ADMIN privilege is
       needed,	otherwise the caller must have ADMIN privilege in the Cupv database.  To change the group ID, the effective user ID of the process
       must match the owner ID of the file and the new group must be in the list of groups the caller belong to or  the  caller  must  have  ADMIN
       privilege in the Cupv database.

RETURN VALUE

       This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

ERRORS

       EPERM	    The effective user ID does not match the owner of the file and the caller does not have ADMIN privilege in the Cupv database.

       ENOENT	    The named file/directory does not exist or is a null pathname.

       EACCES	    Search permission is denied on a component of the path prefix.

       EFAULT	    path is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       EINVAL	    new_uid or new_gid is invalid.

       ENAMETOOLONG The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.
