Determine whether the simulation time is equal to the start time.
boolean_T ssIsFirstInitCond(SimStruct *S)
SimStruct representing an S-Function block.
The Boolean value
true if the current simulation time is equal
to the simulation start time. Otherwise, returns
If this S-function resides in an enabled subsystem configured to reset states,
and if the enabled system is enabled at the start time, then
mdlInitializeConditions is called a second time and the
Boolean value of
mdlInitializeConditions to determine if the callback
is being invoked at the start of the simulation.
