CPX_CALLBACKCONTEXT_THREAD_DOWN

Generic callback at thread end

#defineCPX_CALLBACKCONTEXT_THREAD_DOWN0x0004

Description

This constant is used to specify CPLEX generic callback invocation when CPLEX de-activates a thread. Note that this notification is about thread de-activation, not thread destruction. CPLEX can use thread pools, in which case thread destruction and thread de-activation are two very different events.

This context is the counterpart of CPX_CALLBACKCONTEXT_THREAD_UP.

The constant is used in two different ways:
  • As a value passed into the generic callback function to specify in which context the generic callback is invoked.
  • Bitwise ORed into the where argument of the CPXXcallbacksetfunc and CPXcallbacksetfunc routine to specify in which situations CPLEX should invoke the generic callback.
