NAME    [Toc]    [Back]

     glXQueryHyperpipeNetworkSGIX - query the physical connectivity of the
     hardware

C SPECIFICATION    [Toc]    [Back]

     GLXHyperpipeNetworkSGIX * glXQueryHyperpipeNetworkSGIX( Display * dpy,
							     int *npipes )

PARAMETERS    [Toc]    [Back]

     dpy     Specifies the connection to the X server.


     npipes  Returns the number	of elements in the array
	     GLXHyperpipeNetworkSGIX *.

DESCRIPTION    [Toc]    [Back]

     glXQueryHyperpipeNetworkSGIX is part of the SGIX_hyperpipe	extension.

     glXQueryHyperpipeNetworkSGIX is a query to	determine the physical
     connectivity of the hardware. It returns a	list of	pipes on the hyperpipe
     network.

     There may be more than one	hyperpipe network in the system. The networks
     are numbered sequentially from 0. The list	returned by
     glXQueryHyperpipeNetworkSGIX indicates the	physical hyperpipe network
     number associated with the	pipe.  The list	returned by this query is
     sorted on the physical hyperpipe network number.

     typedef struct {

     char  pipeName[GLX_HYPERPIPE_PIPE_NAME_LENGTH]; /*	The string identifies
     a pipe uniquely and is of the form	":display.screen"*/

     int  networkId; /*	identifies a unique physical hyperpipe network*/

     } GLXHyperipeNetwork;



     Use XFree to free the array returned by glXQueryHyperpipeNetworkSGIX.

ERRORS    [Toc]    [Back]

     Returns an	array of pipes and their associated hyperpipe network number.

     Returns NULL if there is no hyperpipe network in the system.

MACHINE	DEPENDENCIES
     GLX_SGIX_hyperpipe	extension is currently supported only on IR2/DPLEX.
     On	IR2/DPLEX the pipes in a given hyperpipe network have to be used in
     the order that they are connected.	There are further restrictions
     depending on whether the pipes are	connected in a ring or chain.
