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.
