NAMEglXQueryHyperpipeBestAttribSGIX - query best hyperpipe attributes
C SPECIFICATION
int glXQueryHyperpipeBestAttribSGIX( Display *dpy,
int timeSlice,
int attrib,
int size,
void *attribList,
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.
attribList Pointer to array desired attributes.
returnAttribList Pointer to block of memory for best attributes to be
returned.
DESCRIPTIONglXQueryHyperpipeBestAttribSGIX is part of the SGIX_hyperpipe extension.
Hyperpipe hardware may have constraints on the attributes available
through the glXHyperpipeAttribSGIX command.
glXQueryHyperpipeBestAttribSGIX uses the constraints on attribList to
come up with the best possible attributes, and returns them in
returnAttribList.
attrib is one of the following:
GLX_PIPE_RECT 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. attribList should hold an array of
GLXPipeRects, one per pipe in the given timeSlice.

returnAttribList should point to a block of memory
big enough to hold the GLXPipeRects.
GLX_PIPE_RECT_LIMITS Queries the maximum height and width of the
subrectangles of the given timeSlice.
glXQueryHyperpipeBestAttribSGIX 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.
MACHINE DEPENDENCIESglXQueryHyperpipeBestAttribSGIX is currently supported only on
InfinitePerformance systems.
