CPXXcallbackabort and CPXcallbackabort

Aborts a CPLEX solve from a callback.

int CPXXcallbackabort( CPXCALLBACKCONTEXptrcontext )

int CPXcallbackabort( CPXCALLBACKCONTEXptrcontext )

Description

This routine asks CPLEX to abort the ongoing solve at the next possible point.

Warning: For callbacks in the context CPX_CALLBACKCONTEXT_THREAD_DOWN this routine is a "no-op"; that is, the routine does nothing. A solve cannot be aborted from this context.

Warning: If this routine is called from a thread that currently executes speculative code, and the current context is not CPX_CALLBACKCONTEXT_GLOBAL_PROGRESS, then the request to abort may be ignored. Use CPXXsetterminate and CPXsetterminate if you want to make sure CPLEX terminates even in that case.

Arguments

context: The callback context as passed into the callback function.
