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


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

specifies the logical pathname relative to the current LFC directory or the full LFC pathname.
specifies the number of entries present in the buffer.
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; };
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.
is the user or group numeric id.
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.


This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.


The effective user ID does not match the owner of the file and the caller does not have ADMIN privilege in the Cupv database.
The named file/directory does not exist or is a null pathname.
Search permission is denied on a component of the path prefix.
path or acl is a NULL pointer.
A component of path prefix is not a directory.
nentries is not greater than zero or is greater than CA_MAXACLENTRIES or the ACL entries are not valid.
The name server database is full.
The length of path exceeds CA_MAXPATHLEN or the length of a path component exceeds CA_MAXNAMELEN.
Host unknown.
