XAddHost(3)			XLIB FUNCTIONS			   XAddHost(3)

NAME
       XAddHost, XAddHosts, XListHosts, XRemoveHost, XRemoveHosts, XSetAccess‐
       Control, XEnableAccessControl, XDisableAccessControl, XHostAddress,
       XServerInterpretedAddress - control host access and host control struc‐
       ture

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

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

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

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

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

       int XSetAccessControl(Display *display, int mode);

       int XEnableAccessControl(Display *display);

       int XDisableAccessControl(Display *display);

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 EnableAccess or DisableAc‐
		 cess.

       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 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 dis‐
       abled.  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 mem‐
       ory 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 con‐
       trol 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, FamilyInternet6,
       FamilyServerInterpreted, FamilyDECnet, or FamilyChaos.  The length mem‐
       ber specifies the length of the address in bytes.  The address member
       specifies a pointer to the address.

       For the ServerInterpreted family, the length is ignored and the address
       member is a pointer to a XServerInterpretedAddress structure which con‐
       tains:

       typedef struct {
	    int typelength;	     /* length of type string, in bytes */
	    int valuelength;	     /* length of value string, in bytes */
	    char *type;		     /* pointer to where to find the type string */
	    char *value;	     /* pointer to where to find the address */
       } XServerInterpretedAddress;

       The type and value members point to strings representing the type and
       value of the server interpreted entry.  These strings may not be NULL-
       terminated so care should be used when accessing them.  The typelength
       and valuelength members specify the length in byte of the type and
       value strings.

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.
