XRemoveHosts()															    XRemoveHosts()

Name
  XRemoveHosts - remove multiple hosts from the access control list.

Synopsis
  XRemoveHosts(display, hosts, num_hosts)
	Display *display;
	XHostAddress *hosts;
	int num_hosts;

Arguments
  display   Specifies a connection to an X server; returned from XOpenDisplay().

  hosts     Specifies the list of hosts that are to be removed.

  num_hosts Specifies the number of hosts that are to be removed.

Description
  XRemoveHosts()  removes  each  specified host from the access control list of the connected server.  The server must be on the same host as
  the process that call XRemoveHosts(), in order to change the access control list.

  If you remove your machine from the access control list, you can no longer connect to that server, and there is no way back from this  call
  except to log out, edit the access control file, and reset the server.

  The address data must be a valid address for the type of network in which the server operates, as specified in the family member.

  For  TCP/IP,	the address should be in network byte order.  For the DECnet family, the server performs no automatic swapping on the address
  bytes.  A Phase IV address is two bytes long.  The first byte contains the least significant eight bits of the  node	number.   The  second
  byte contains the most significant two bits of the node number in the least significant two bits of the byte, and the area in the most sig-
  nificant six bits of the byte.

  For more information on access control lists, see Volume One, Chapter 15, Other Programming Techniques.

Structures
     typedef struct {
	 int family;	    /* for example Family Internet */
	 int length;	    /* length of address, in bytes */
	 char *address;     /* pointer to where to find the bytes */
     } XHostAddress;

     /* constants used for family member of XHostAddress */
     #define FamilyInternet	 0
     #define FamilyDECnet	 1
     #define FamilyChaos	 2

Errors
  BadAccess
  BadValue

NAME

       XAddHost,  XAddHosts, XListHosts, XRemoveHost, XRemoveHosts, XSetAccessControl, XEnableAccessControl, XDisableAccessControl, XHostAddress -
       control host access and host control structure

SYNOPSIS

       XAddHost(display, host)
	       Display *display;
	       XHostAddress *host;

       XAddHosts(display, hosts, num_hosts)
	       Display *display;
	       XHostAddress *hosts;
	       int num_hosts;

       XHostAddress *XListHosts(display, nhosts_return, state_return)
	       Display *display;
	       int *nhosts_return;
	       Bool *state_return;

       XRemoveHost(display, host)
	       Display *display;
	       XHostAddress *host;

       XRemoveHosts(display, hosts, num_hosts)
	       Display *display;
	       XHostAddress *hosts;
	       int num_hosts;

       XSetAccessControl(display, mode)
	       Display *display;
	       int mode;

       XEnableAccessControl(display)
	       Display *display;

       XDisableAccessControl(display)
	       Display *display;

ARGUMENTS

       Specifies the connection to the X server.  Specifies the host that is to be added or removed.  Specifies each host that is to be  added	or
       removed.   Specifies  the  mode.  You  can pass EnableAccess or DisableAccess.  Returns the number of hosts currently in the access control
       list.  Specifies the number of hosts.  Returns the state of the access control.

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 struc-
       tures 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.

STRUCTURES

       The XHostAddress structure contains:

       typedef struct {
	       int family;   /* for example FamilyInternet */
	       int length;   /* length of address, in bytes */
	       char *address;/* pointer to where to find the address */ } XHostAddress;

       The family member specifies which protocol address family to use (for example, TCP/IP or DECnet) and can be  FamilyInternet,  FamilyDECnet,
       or FamilyChaos. The length member specifies the length of the address in bytes. The address member specifies a pointer to the address.

DIAGNOSTICS

       A  client  attempted  to modify the access control list from other than the local (or otherwise authorized) host.  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.
