1 HXCOMM Use DEFHEADING() to define headings in both help text and texi
2 HXCOMM Text between STEXI and ETEXI are copied to texi version and
3 HXCOMM discarded from C version
4 HXCOMM DEF(command, args, callback, arg_string, help) is used to construct
5 HXCOMM monitor commands
6 HXCOMM HXCOMM can be used for comments, discarded from both texi and C

413 @item count
414 is the number of items to be dumped.
415
416 @item format

418 c (char) or i (asm instruction).
419
420 @item size
421 can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
422 @code{h} or @code{w} can be specified with the @code{i} format to
423 respectively select 16 or 32 bit code instruction size.

1178 @item acl_add @var{aclname} @var{match} @code{allow|deny} [@var{index}]
1179 @findex acl_add
1180 Add a match rule to the access control list, allowing or denying access.
1181 The match will normally be an exact username or x509 distinguished name,
1182 but can optionally include wildcard globs. eg @code{*@@EXAMPLE.COM} to
1183 allow all users in the @code{EXAMPLE.COM} kerberos realm. The match will
1184 normally be appended to the end of the ACL, but can be inserted
1185 earlier in the list if the optional @var{index} parameter is supplied.
