NAME
dpns_setacl - set DPNS directory/file access control lists
SYNOPSIS
#include <sys/types.h>
#include "dpns_api.h"
int dpns_setacl (const char *path,
int nentries,
struct dpns_acl *acl)
DESCRIPTION
dpns_setacl
sets the Access Control List associated with a DPNS directory/file.
- path
-
specifies the logical pathname relative to the current DPNS directory or
the full DPNS pathname.
- nentries
-
specifies the number of entries present in the buffer.
- acl
-
is a pointer to an array of dpns_acl structures provided by the application.
struct dpns_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.
