SYNOPSIS

     #include <sys/types.h>
     #include <sys/acl.h>

     int
     acl_add_flag_np(acl_flagset_t flagset_d, acl_flag_t flag);

DESCRIPTION

     The acl_add_flag_np() function is a nonstandard extension that adds the
     flag contained in flag to the flag set flagset_d.

     Note: it is not considered an error to attempt to add flags that already
     exist in the flag set.

RETURN VALUES

     The acl_add_flags_np() function returns the value 0 if successful; other-
     wise the value -1 is returned and the global variable errno is set to
     indicate the error.

ERRORS

     The acl_add_flags_np() function fails if:

     [EINVAL]           Argument flagset_d is not a valid descriptor for a
                        flag set.  Argument flag does not contain an
                        acl_flag_t value valid for the flagset flagset_d.
