glXQueryHyperpipeNetworkSGIX(3G) OpenGL Reference - GLX 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 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 Returns an array of pipes and their associated hyperpipe network number. Returns NULL if there is no hyperpipe network in the system. Page 1 glXQueryHyperpipeNetworkSGIX(3G) OpenGL Reference - GLX 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. SEE ALSO glXHyperpipeConfigSGIX glXQueryHyperpipeConfigSGIX glXBindHyperpipeSGIX Page 2[top]
