  40 .Sh SYNOPSIS
  41 .In sys/types.h
  42 .In sys/acl.h
  43 .Ft int
  44 .Fn acl_delete_fd_np "int filedes" "acl_type_t type"
  45 .Ft int
  46 .Fn acl_delete_file_np "const char *path_p" "acl_type_t type"
  47 .Ft int
  48 .Fn acl_delete_link_np "const char *path_p" "acl_type_t type"
  49 .Sh DESCRIPTION
  50 The
  51 .Fn acl_delete_fd_np ,
  52 .Fn acl_delete_file_np ,
  53 and
  54 .Fn acl_delete_link_np
  55 each allow the deletion of an ACL from a file.
  56 These functions are non-portable extensions
  57 that permit the deletion of arbitrary ACL types from a file/directory
  58 either by path name or file descriptor.
  59 The
  60 .Fn _file
  61 variations follow a symlink if it occurs in the last segment of the
  62 path name; the
  63 .Fn _link
  64 variations operate on the symlink itself.
  65 .Sh RETURN VALUES
  66 .Rv -std
  67 .Sh ERRORS
  68 If any of the following conditions occur, these functions shall return -1
  69 and set
  70 .Va errno
  71 to the corresponding value:
  72 .Bl -tag -width Er
  73 .It Bq Er EACCES
  74 Search permission is denied for a component of the path prefix, or the
  75 object exists and the process does not have appropriate access rights.
  76 .It Bq Er EBADF
  77 The
  78 .Va fd
  79 argument is not a valid file descriptor.
  80 .It Bq Er EINVAL
  81 The ACL type passed is invalid for this file object.
  82 .It Bq Er ENAMETOOLONG
  83 A component of a pathname exceeded 255 characters, or an
  84 entire path name exceeded 1023 characters.
  85 .It Bq Er ENOENT
  86 The named object does not exist, or the
  87 .Va path_p
  88 argument points to an empty string.
  89 .It Bq Er ENOMEM
  90 Insufficient memory available to fulfill request.
  91 .It Bq Er ENOTDIR
  92 A component of the path prefix is not a directory.
  93 .Pp
  94 Argument
  95 .Va path_p
  96 must be a directory, and is not.
  97 .It Bq Er EOPNOTSUPP
  98 The file system does not support ACL deletion.
  99 .It Bq Er EPERM

 101 to delete an ACL.
