MATLAB Embedded Coder C-Caller Block: Custom type function variable arguments

Hello,

i want to use my C-Code in MATLAB Embedded Coder. I currently use the C-Caller Block to integrate my C-Code respective my C-functions. The problem is that I use custom data types for function arguments and the "Block Parameters: C Caller" does not recognise my function. When I change the function argument in my C-Code to e.g. int the C-Caller Block immediately shows up the function. How to avoid that issue?

Thank you and kind regards

Clemens

C Caller directly calls the function from Simulink. So, the inputs to the function must be simulink compatible. If any of the inputs of the C Function cannot be mapped to a simulink supported type, then the function will not show up.

Alternatively, you can use the C Function block, which allows you freedom in calling functions that are directly unsupported in Simulink.
