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.
