 37  .Sh SYNOPSIS
 38  .In sys/types.h
 39  .In sys/acl.h
 40  .Ft int
 41  .Fn acl_create_entry "acl_t *acl_p" "acl_entry_t *entry_p"
 42  .Ft int
 43  .Fn acl_create_entry_np "acl_t *acl_p" "acl_entry_t *entry_p" "int entry_index"
 44  .Sh DESCRIPTION
 45  The
 46  .Fn acl_create_entry
 47  function
 48  is a POSIX.1e call that creates a new ACL entry in the ACL
 49  pointed to by
 50  .Fa acl_p .
 51  The function will return in
 52  .Fa entry_p
 53  a descriptor for this ACL entry.
 54  .Pp
 55  The
 56  .Fn acl_create_entry_np
 57  function is a non-portable extension which allows the caller to specify the
 58  position of the created entry within the ACL.  If
 59  .Fa entry_index
 60  is
 61  .Dv ACL_FIRST_ENTRY
 62  the entry will be created at the head of the ACL.  If
 63  .Fa entry_index
 64  is
 65  .Dv ACL_LAST_ENTRY
 66  the entry will be created at the end of the ACL.  After inserting an ACL entry with an
 67  .Fa entry_index
 68  other than
 69  .Dv ACL_LAST_ENTRY
 70  the behaviour of any acl_entry_t's previously obtained from the ACL
 71  by
 72  .Fn acl_create_entry
 73  or
 74  .Fn acl_get_entry
 75  is undefined.
 76  .Sh RETURN VALUES
 77  .Rv -std acl_create_entry
 78  .Sh ERRORS
 79  The
 80  .Fn acl_create_entry
 81  and
 82  .Fn acl_create_entry_np
 83  functions fail if:
 84  .Bl -tag -width Er
 85  .It Bq Er EINVAL
 86  Argument
 87  .Fa acl_p
 88  does not point to a pointer to a valid ACL.
 89  .It Bq Er ENOMEM
 90  The ACL working storage requires more memory than is
 91  allowed by the hardware or system-imposed memory
 92  management constraints.
 93  .It Bq Er ERANGE
 94  The
 95  .Fa entry_index
 96  argument to
 97  .Fn acl_create_entry_np
 98  is greater than the number of entries in the ACL.
