Arguments
       display	 Specifies the connection to the X server.

       host	 Specifies the host that is to be added or removed.

       hosts	 Specifies each host that is to be added or removed.

       mode	 Specifies the mode.  You can pass or

       nhosts_return
		 Returns the number of hosts currently in the access control list.

       num_hosts Specifies the number of hosts.

       state_return
		 Returns the state of the access control.

Description
       The function adds the specified host to the access control list for that display.  The server must be on the same host as the client issu-
       ing the command, or a error results.

       can generate and errors.

       The function adds each specified host to the access control list for that display.  The server must be on the same host as the client issu-
       ing the command, or a error results.

       can generate and errors.

       The function returns the current access control list as well as whether the use of the list at connection setup was enabled or disabled.
       allows a program to find out what machines can make connections.  It also returns a pointer to a list of host structures that were allo-
       cated by the function.  When no longer needed, this memory should be freed by calling

       The 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 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.

       can generate and errors.

       The 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 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.

       can generate and errors.

       The function either enables or disables the use of the access control list at each connection setup.

       can generate and errors.

       The function enables the use of the access control list at each connection setup.

       can generate a error.

       The function disables the use of the access control list at each connection setup.

       can generate a error.

Structures
       The structure contains:

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

       The family member specifies which protocol address family to use (for example, TCP/IP or DECnet) and can be or 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.
