To inline an S-function during code generation, you indeed need to create a TLC file that specifies how the S-function should be translated into C code. Below is a simple example of a TLC file that inlines an S-function using a custom C function named "timestwo". This example S-function has one input and one output.
%assign outPtr = LibBlockOutputSignalAddr(0, "", "", 0)
%assign inPtr = LibBlockInputSignalAddr(0, "", "",0)
%assign numEls = LibBlockOutputSignalWidth(0)
timestwo(%<inPtr>,%<outPtr>,%<numEls>);
After creating the TLC file, make sure to configure the S-Function block to use the TLC file.
You can learn more about Inlining S-Function using TLC files by following this documentation.
