Determine whether a block has requested block reduction before the simulation has begun and whether it has actually been reduced after the simulation loop has begun
uint_T ssGetBlockReduction(SimStruct *S)
SimStruct representing an S-Function block.
The result of this function depends on when it is invoked. When invoked before the
simulation loop has started, i.e., in
earlier, this macro returns
1 if the block has previously
requested that it be reduced. When invoked after the simulation loop has begun, this
1 if the block has actually been reduced, i.e.,
eliminated from the list of blocks to be executed during the simulation loop.
Use to determine if a block requested block reduction, or to determine if the block has already been reduced.
If a block has been reduced, the only callback method invoked for the block
after the simulation loop has begun is the block's
mdlTerminate method. Further,
the Simulink® engine invokes the
mdlTerminate method only if
the block has set its
SS_OPTION_CALL_TERMINATE_ON_EXIT option, using
ssSetOptions. Thus, if your
block needs to determine whether it has actually been reduced, it must set the
SS_OPTION_CALL_TERMINATE_ON_EXIT option before the
simulation loop has begun and invoke
