NAME    [Toc]    [Back]

     glXQueryHyperpipeConfigSGIX - Query the details of	a hyperpipe

C SPECIFICATION    [Toc]    [Back]

     GLXHyperpipeConfigSGIX * glXQueryHyperpipeConfigSGIX( Display *dpy,
							   int hpId,
							   int *npipes )

PARAMETERS    [Toc]    [Back]

     dpy     Specifies the connection to the X server.

     hpId    The hyperpipe id to be queried. Hyperpipe ids are assigned

DESCRIPTION    [Toc]    [Back]

     glXQueryHyperpipeConfigSGIX is part of the	SGIX_hyperpipe extension.

     glXQueryHyperpipeConfigSGIX is a query to determine the details of	a
     hyperpipe configuration.  Hyperpipe configurations	can be created by

     glXQueryHyperpipeConfigSGIX returns an array of type
     GLXHyperpipeConfigSGIX. Each entry	within the array represents a pipe and
     GLXHyperpipeConfigSGIX specifies its details.

     typedef struct {

     char pipeName[GLX_HYPERPIPE_PIPE_NAME_LENGTH];  /*	String */

     int channel; /* The channel  number associated with the pipe */

     unsigned int participationType; /*	participationType is a bitmask
     describing	the  attributes	of a participating pipe. The bitmask may
     contain one or more  of the following attributes:

     int timeSlice; /* The timeSlice is	ignored	if the	participationType is

     } GLXHyperpipeConfigSGIX;

     Use XFree to free the array returned by glXQueryHyperpipeConfigSGIX.

RETURN VALUES    [Toc]    [Back]

     Returns NULL if the hyperpipe id specified	by hpId	is invalid.

     Returns an	array of type GLXHyperpipeConfigSGIX if	the call succeeds.

     GLX_SGIX_hyperpipe	extension is currently supported only on IR2/DPLEX.

     On	IR2/DPLEX the pipes have to participate	in the order that they are
