Syntax

boolean_T ssSetNumInputPorts(SimStruct *S, int_T nInputPorts)

Arguments

S

SimStruct that represents an S-Function block.

nInputPorts

Number of input ports on the block represented by S. Must be a nonnegative integer.

Returns

The Boolean value true if successful. Otherwise, returns false.

Description

Use in mdlInitializeSizes to set the number of input ports to a nonnegative integer. Invoke it using

if (!ssSetNumInputPorts(S,nInputPorts)) return;

where ssSetNumInputPorts returns false if nInputPorts is negative or an error occurs while creating the ports.

Languages

C, C++
