XtAppReleaseCacheRefs - decrement reference counts for resources
#include <X11/Intrinsic.h>
void XtAppReleaseCacheRefs(XtAppContext app_context,
    XtCacheRef* refs);
  - app_context
- Specifies the application context.
- refs
- Specifies the list of cache references to be released.
XtAppReleaseCacheRefs decrements the reference count for the conversion
  entries identified by the refs argument. This argument is a pointer to
  a NULL-terminated list of XtCacheRef values. If any reference count
  reaches zero, the destructor, if any, will be called and the resource removed
  from the conversion cache.
