ssSetNumOutputPorts - Specify the number of output ports that a block has

Syntax

boolean_T ssSetNumOutputPorts(SimStruct *S, int_T nOutputPorts)

Arguments

S

SimStruct representing an S-Function block.

nOutputPorts

Number of output 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 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.

Languages

C, C++

Example

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