Syntax

InputPtrsType ssGetInputPortSignalPtrs(SimStruct *S, int_T port)

Arguments

Returns

Pointer to an array of signal element pointers for the specified input port.

Description

Use to obtain pointers to an input port's signal elements. If the input port width is 5, this function returns a pointer to a 5-element pointer array. Each element in the pointer array points to the specific element of the input signal.

You must usessGetInputPortRealSignalPtrsto get pointers to signals of typedouble(real_T).

Use this function only for non-contiguous input. If you have contiguous input, use thessGetInputPortSignalfunction.

Languages

C, C++

Example

Assume that the input port data types areint8_T.

int_T nInputPorts = ssGetNumInputPorts(S); for (i = 0; i < nInputPorts; i++) { InputPtrsType u = ssGetInputPortSignalPtrs(S,i); InputInt8PtrsType uPtrs = (InputInt8PtrsType)u; int_T nu = ssGetInputPortWidth(S,i); for (j = 0; j < nu; j++) { /* uPtrs[j] is an int8_T pointer that points to the j-th element of the input signal. */ UseInputInSomeFunction(*uPtrs[j]); }

See the S-functionsfun_dtype_io.cused insfcndemo_dtype_iofor a complete example that uses this function.
