  36 .Sh SYNOPSIS
  37 .In sys/types.h
  38 .In sys/acl.h
  39 .Ft int
  40 .Fn acl_set_qualifier "acl_entry_t entry_d" "const void *tag_qualifier_p"
  41 .Sh DESCRIPTION
  42 The
  43 .Fn acl_set_qualifier
  44 function
  45 is a POSIX.1e call that sets the qualifier of the tag for the ACL entry
  46 .Fa entry_d
  47 to the value referred to by
  48 .Fa tag_qualifier_p .
  49 .Pp
  50 The tag type of the ACL entry, as previously set with
  51 .Xr acl_set_tag_type 3 ,
  52 must be either
  53 .Dv ACL_EXTENDED_ALLOW
  54 or
  55 .Dv ACL_EXTENDED_DENY ,
  56 and
  57 .Fa tag_qualifier_p
  58 should be a pointer to a global unique identifier (of type
  59 .Ft guid_t ) .
  60 .Sh RETURN VALUES
  61 .Rv -std acl_set_qualifier
  62 .Sh ERRORS
  63 The
  64 .Fn acl_set_qualifier
  65 function fails if:
  66 .Bl -tag -width Er
  67 .It Bq Er EINVAL
  68 Argument
  69 .Fa entry_d
  70 is not a valid descriptor for an ACL entry.  The tag type of the
  71 ACL entry
  72 .Fa entry_d
  73 is not
  74 .Dv ACL_EXTENDED_ALLOW
  75 or
  76 .Dv ACL_EXTENDED_DENY .
  77 The value pointed to by
  78 .Fa tag_qualifier_p
  79 is not valid.
  80 .It Bq Er ENOMEM
  81 The value to be returned requires more memory than is allowed
  82 by the hardware or system-imposed memory management constraints.
