Forces the cache to be flushed.
AIXwindows Library (libXm.a)
_XFlushGCCache(DisplayPtr, GraphicsContext) Display *DisplayPtr; GC GraphicsContext;
Graphics context (GC) caching is performed by the library to allow merging of independent change requests to the same GC into single protocol requests. This is typically called a write-back cache. Any extension routine whose behavior depends on the contents of a GC must flush the GC cache to make sure the server has up-to-date contents in its GC.
The FlushGC macro checks the dirty bits in the library's GC structure and calls the _XFlushGCCache extension subroutine if any elements have changed. The FlushGC macro is defined as follows:
FlushGC(DisplayPtr, GraphicsContext) Display *DisplayPtr; GC GraphicsContext;
Note: If you extend the GC to add additional resource ID components, ensure that the library stub sends the change request immediately. This is because a client can free a resource immediately after using it, so if you only store the value in the cache without forcing a protocol request, the resource might be destroyed before being set into the GC. You can use the _XFlushGCCache extension function to force the cache to be flushed.
