ssGetTaskTime

Get the current time for the current task

Syntax

time_T ssGetTaskTime(SimStruct *S, st_index)

Arguments

S

SimStruct that represents an S-Function block.

st_index

Index of the sample time corresponding to the task for which the current time is to be returned.

Returns

A value of type time_T.

Description

Use to determine the current time (time_T) of the task corresponding to the sample rate specified by st_index. You can use this macro in mdlOutputs and mdlUpdate to compute the output of your block. See matlabroot/extern/include/tmwtypes.h for a description of the time_T data type.

The ssGetTaskTime macro should be called only inside an ssIsSampleHit check when you have multirate S-Functions. It will not give the correct results if called with the tid passed into mdlOutputs.

Languages

C, C++

Examples

The following example illustrates a correct usage of this macro:

static void mdlOutputs( SimStruct *S, int_T tid ) 
{
	double t; 
	if(ssIsSampleHit(S,0,tid)) { 
		t = ssGetTaskTime(S,0); 
		ssPrintf("Task 0 sample hit in %s time = %g\n",
					ssGetPath(S),t); 
	} 
	if(ssIsSampleHit(S,1,tid)) { 
		t = ssGetTaskTime(S,1); 
		ssPrintf("Task 1 sample hit in %s time = %g\n",
					ssGetPath(S),t); 
	} 
}
