DESCRIPTION
The XAddHost function adds the specified host to the access
control list for that display. The server must be on the
same host as the client issuing the command, or a BadAccess
error results.
XAddHost can generate BadAccess and BadValue errors.
The XAddHosts function adds each specified host to the
access control list for that display. The server must be on
the same host as the client issuing the command, or a
BadAccess error results.
XAddHosts can generate BadAccess and BadValue errors.
The XListHosts function returns the current access control
list as well as whether the use of the list at connection
setup was enabled or disabled. XListHosts allows a program
to find out what machines can make connections. It also
returns a pointer to a list of host structures that were
allocated by the function. When no longer needed, this
memory should be freed by calling XFree.
The XRemoveHost function removes the specified host from the
access control list for that display. The server must be on
the same host as the client process, or a BadAccess error
results. If you remove your machine from the access list,
you can no longer connect to that server, and this operation
cannot be reversed unless you reset the server.
XRemoveHost can generate BadAccess and BadValue errors.
The XRemoveHosts function removes each specified host from
the access control list for that display. The X server must
be on the same host as the client process, or a BadAccess
error results. If you remove your machine from the access
list, you can no longer connect to that server, and this
operation cannot be reversed unless you reset the server.
XRemoveHosts can generate BadAccess and BadValue errors.
The XSetAccessControl function either enables or disables
the use of the access control list at each connection setup.

DIAGNOSTICS
BadAccess A client attempted to modify the access control
list from other than the local (or otherwise
authorized) host.
BadValue Some numeric value falls outside the range of
values accepted by the request. Unless a specific
range is specified for an argument, the full range
defined by the argument's type is accepted. Any
argument defined as a set of alternatives can
generate this error.
