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.
XSetAccessControl can generate
BadAccess and BadValue errors.
The XEnableAccessControl function enables the use of
the access control list at each connection setup.
XEnableAccessControl can generate a BadAccess error.
The XDisableAccessControl function disables the use of
the access control list at each connection setup.
XDisableAccessControl can generate a BadAccess error.
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.
