Specify the number of output ports that a block has
boolean_T ssSetNumOutputPorts(SimStruct *S, int_T nOutputPorts)
SSimStruct representing an S-Function block.
nOutputPortsNumber of output 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 output ports to
a nonnegative integer. Invoke the function using
if (!ssSetNumOutputPorts(S,nOutputPorts)) return;
where ssSetNumOutputPorts returns 0 if
nOutputPorts is negative or an error occurs while
creating the ports. When this occurs, and you return out of your S-function, the
Simulink® engine displays an error message.

See the S-function sfun_port_constant.c used in sfcndemo_port_constant.
