PEXSetReflectionAttributes(3) — Subroutines

Name

PEXSetReflectionAttributes - Set Surface Reflection Attributes

Synopsis

void PEXSetReflectionAttributes(Display ∗display, XID resource_id, PEXOCRequestType req_type, PEXReflectionAttributes ∗attributes)

Arguments

displayA pointer to a display structure returned by a successful XOpenDisplay call.

resource_idThe resource identifier of the renderer or structure.

req_typeThe request type for the output command (PEXOCRender, PEXOCStore, PEXOCRenderSingle or PEXOCStoreSingle).

attributesThe surface reflection attributes.

Returns

None
