Specify the number of input ports that a block has
boolean_T ssSetNumInputPorts(SimStruct *S, int_T nInputPorts)
SSimStruct representing an S-Function block.
nInputPortsNumber of input ports on the block represented by
S. Must be a nonnegative integer.
The Boolean value true if successful. Otherwise, returns
false.
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.
