NAMEglXQueryHyperpipeAttribSGIX - query current hyperpipe attributes
C SPECIFICATION
int glXQueryHyperpipeAttribSGIX( Display *dpy,
int timeSlice,
int attrib,
int size,
void *returnAttribList )
PARAMETERS
dpy Specifies the connection to the X server.
timeSlice Specifies the timeslice whose attributes are to be
queried.
attrib Specifies the attribute being queried.
size Specifies the size of the attribute block.
returnAttribList Pointer to block of memory for attributes.
DESCRIPTIONglXQueryHyperpipeAttribSGIX is part of the SGIX_hyperpipe extension.
glXQueryHyperpipeAttribSGIX queries the currently bound hyperpipe for the
attribute listed in attrib. attrib is one of the following:
GLX_PIPE_RECT_SGIX Queries the subrectangles that constitute the
hyperpipe output during timeSlice. An array of
GLXPipeRects will be returned in the memory pointed
to by returnAttribList. There will be one
GLXPipeRect per pipe participating in the given
timeSlice. returnAttribList should point to a block
of memory big enough to hold the GLXPipeRects.
GLX_PIPE_RECT_LIMITS_SGIX
Queries the maximum height and width of the
subrectangles of the given timeSlice.
GLX_HYPERPIPE_STEREO_MODE_SGIX
Queries whether the hyperpipe stereo mode is
active. returnAttribList should point to an
integer, which will be 1 if the mode is active, or
0 if it is inactive.

GLX_HYPERPIPE_PIXEL_AVERAGE_SGIX
Queries whether the hyperpipe stereo mode is
active. returnAttribList should point to an
integer, which will be 1 if the mode is active, or
0 if it is inactive.
glXQueryHyperpipeAttribSGIX works with a direct context only.
RETURN VALUES
Returns 0 on success.
Returns GLX_BAD_VALUE if the attribute specified is incorrect, or if one
or more of the elements specified in the attribute list is incorrect.
Returns GLX_BAD_HYPERPIPE_SGIX if the hyperpipe bound to the current
context is invalid or absent. GLX_BAD_CONTEXT if there is no current
context, or if the current context is not a direct context.
MACHINE DEPENDENCIESglXQueryHyperpipeAttribSGIX is currently supported only on
InfinitePerformance systems.
