+--------------------
+01h,15dec15,rr   Added notifyKernelTask variable to sigevent 
+		 structure (VXW6-85053)
+01g,22jul15,h_k  added objHandleAndClassToObjId(). (VXW6-81821)
+01f,30nov11,jpb  WIND00309548.  sigeventUserToKernel possibly dereferences NULL
+                 pointer.  Fixed build warning.
+01e,28jan11,gls  added sigeventUserToKernel() (WIND00252562)
+01d,04mar10,cww  LP64 adapatation
+01c,23dec09,jpb  Updated for LP64 adaptation.
+01b,10jul06,gls  added the sigeventLibInit() prototype
+                 updated copyright
