NAME

       lfc_chown - change owner and group of a LFC directory/file in the name server

SYNOPSIS

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

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

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

DESCRIPTION

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

       lfc_lchown is identical to lfc_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 LFC directory or the full LFC 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.

NAME

       lfc_setacl - set LFC directory/file access control lists

SYNOPSIS

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

       int lfc_setacl (const char *path, int nentries, struct lfc_acl *acl)

DESCRIPTION

       lfc_setacl sets the Access Control List associated with a LFC directory/file.

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

       nentries
	      specifies the number of entries present in the buffer.

       acl    is a pointer to an array of lfc_acl structures provided by the application.

       struct lfc_acl {
	       unsigned char   a_type;
	       int	       a_id;
	       unsigned char   a_perm;
       };

       a_type is the ACL type: CNS_ACL_USER_OBJ, CNS_ACL_USER, CNS_ACL_GROUP_OBJ, CNS_ACL_GROUP, CNS_ACL_MASK or CNS_ACL_OTHER.  Types for default
	      entries are obtained by OR'ing the flag CNS_ACL_DEFAULT with one of the above types.

       a_id   is the user or group numeric id.

       a_perm is the access permission in numeric form obtained by OR'ing some of the bits S_IROTH, S_IWOTH, S_IXOTH.

       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.

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 or acl is a NULL pointer.

       ENOTDIR	    A component of path prefix is not a directory.

       EINVAL	    nentries is not greater than zero or is greater than CA_MAXACLENTRIES or the ACL entries are not valid.

       ENOSPC	    The name server database is full.

       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.
