Writing S-Functions

ssDisableSystemWithTid

Disable a function-call subsystem connected to this S-function block.

Syntax

• ssDisableSystemWithTid(SimStruct *S, element, tid)
  

Arguments

S
   SimStruct representing an S-Function block.

element
   Index of the output port element corresponding to the function-call subsystem.

Description

Use in mdlOutputs to disable a function-call subsystem connected to the S-function. The invoking syntax is

• if (!ssDisableSystemWithTid(S, element, tid)) {
    /* Error occurred which will be reported by      Simulink */
    return;
  }
  

Note    Before invoking this function, the S-function must have specified that it explicitly enables and disables the function-call subsystems that it calls. See ssSetExplicitFCSSCtrl for more information. If the S-function has not done this, invoking ssEnableSystemWithTid results in an error.

This function resets the outputs of any Outport blocks in the function-call subsystem whose Outputs when disabled parameter is set to reset.
