ssGetSampleTime

Get one of an S-function's sample times.

Syntax

time_T ssGetSampleTime(SimStruct *S, int_T sti);

Arguments

S

SimStruct that represents an S-Function block.

sti

Index of the sample time to be returned.

Returns

A time_T value indicating the sample time associated with the index sti.

Description

Use to obtain the sample time of S corresponding to the sample time index sti. See matlabroot/extern/include/tmwtypes.h for a description of the time_T data type.

Note

You cannot call this macro in S-functions that only use port-based sample times. You should use the macros ssGetInputPortSampleTime and ssGetOutputPortSampleTime.

Note

Using ssGetSampleTime for computations can make your S-function sample time dependent. Use ssSetModelReferenceSampleTimeDisallowInheritance so that Simulink^® displays an error when your S-function is used in an inappropriate context.

Languages

C, C++

Examples

The following statement

time_T t = ssGetSampleTime(S, 0);

returns the S-function's current sample time.

See the S-function sfun_zc_sat.c used in sfcndemo_sfun_zc_sat for a complete example that uses this function.
