af_protect3
Atfs protection handling
Usage
#include <atfs.h>
int af_chowner (Af_key *aso, Af_user *owner)
int af_chauthor (Af_key *aso, Af_user *author)
int af_chmod (Af_key *aso, int mode)
Overview
af_chowner and af_chauthor modify the owner and author attribute of an ASO. Only the superuser may change the owner of an object history. The author attribute of an ASO can only be changed by it's owner. The Af_user structure has the following form
typedef struct {
char af_username[MAXUSERNAMELEN];
char af_userhost[MAXHOSTNAMELEN];
char af_userdomain[MAXDOMAIN+1];
} Af_user;
af_chmod changes the mode of an ASO. See chmod(3) for further details.
Diagnostics
Upon error, -1 is returned and af_errno is set to the corresponding error number.
