What is SS_RTW_STORAGE_CUSTOM?

Hello Everyone

I want to create a variant, define in CodeGen .c file. I am using s-func, find SS_RTW_STORAGE_CUSTOM is defined in C:\Program Files\MATLAB\R2024b\simulink\include\rtw_storage.h.

I use it in C code for s-func: ssSetDWorkRTWStorageClass(S, 0, SS_RTW_STORAGE_CUSTOM). But CodeGenerator tells "Unknown error processing storage class: Custom".

Do I miss something to setup custome storage? I certainly want a custom storage like "MEM_CUSTOM_CAL", it works if I use a Simulink.Parameter variant. but how can I use it in s-func by ssSetDWorkxxxxxx or smiliar function.

s-func C code:

ssSetNumDWork(S,1);

ssSetDWorkWidth(S,0,1);

ssSetDWorkDataType(S,0, dataType);

ssSetDWorkName(S,0,dworkName);

ssSetDWorkUsedAsDState(S,0,SS_DWORK_USED_AS_DSTATE);

ssSetDWorkRTWIdentifier(S, 0, dworkName);

ssSetDWorkRTWTypeQualifier(S, 0, "");

ssSetDWorkRTWStorageClass(S, 0, SS_RTW_STORAGE_CUSTOM);

TLC of s-function

%function Outputs(block, system) Output

%openfile buf

/* ===== TLC DWork TEST ===== */

/* DWork information */

%if EXISTS(block.DWork)

%<LibBlockDWork(block.DWork, "", "", "0")> = 0;

%endif

%closefile buf

%<buf>

%endfunction
