NAME
     glXQueryHyperpipeNetworkSGIX - query the physical connectivity of the
     hardware


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


PARAMETERS
     dpy     Specifies the connection to the X server.


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


DESCRIPTION
     glXQueryHyperpipeNetworkSGIX is part of the SGIXhyperpipe 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
     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.
