NAME

       dpns_chmod - change access mode of a DPNS directory/file in the name server

SYNOPSIS

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

       int dpns_chmod (const char *path, mode_t mode)

DESCRIPTION

       dpns_chmod sets the access permission portion of the mode of a DPNS directory/file in the name server to the bit pattern in mode.

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

       mode   is constructed by OR'ing the bits defined in <sys/stat.h> under Unix or  "statbits.h" under Windows/NT:

	      S_ISUID	0004000 	set user ID on execution
	      S_ISGID	0002000 	set group ID on execution
	      S_ISVTX	0001000 	sticky bit
	      S_IRUSR	0000400 	read by owner
	      S_IWUSR	0000200 	write by owner
	      S_IXUSR	0000100 	execute/search by owner
	      S_IRGRP	0000040 	read by group
	      S_IWGRP	0000020 	write by group
	      S_IXGRP	0000010 	execute/search by group
	      S_IROTH	0000004 	read by others
	      S_IWOTH	0000002 	write by others
	      S_IXOTH	0000001 	execute/search by others

       The  effective  user ID of the process must match the owner of the file or the caller must have ADMIN privilege in the Cupv database.  If a
       directory is writable and has the sticky bit set, files/directories within that directory can be removed or renamed only if:

	      the effective user ID of the requestor matches the owner ID of the file or

	      the effective user ID of the requestor matches the owner ID of the directory or

	      the file is writable by the requestor or

	      the requestor has 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.

       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.

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.
