Hi, I'm generating a driver to generate C code, and I need to pass one string from mask to the generated code. Is possible to pass this string from Simulink, with S-function or mytlc.tlc? I have thought that I can pass a string collecting the block name from mytlc.tlc, but it isn't the correct form. Thanks in advance

Yes, I think this should be possible if you register the parameter as nontunable. You will need to implement the mdlRTW method in the S-function and write the parameter using ssWriteRTWParamSettings - the TLC file can access its value from the SFcnParamSettings record . Also, uncheck the "Evaluate" box for the parameter on the Mask .

I dont think this works. I'm missing something trivial, can you please help

S-Function CODE SNIPPET
#define MASK_PARAM_NAME1(S) ssGetSFcnParam(S,1)
#define MASK_PARAM_NAME2(S) ssGetSFcnParam(S,2)
#define MDL_RTW
static void mdlRTW ( SimStruct * S )
{
    const char_T *testTLCStr = "maskParam1TLCName";
    const char_T *maskParam1TLCName = (const char_T *) (mxGetData(MASK_PARAM_NAME1(S)));
    const char_T *maskParam2TLCName = (const char_T *) (mxGetData(MASK_PARAM_NAME2(S)));
    if (!ssWriteRTWParamSettings(S, 2,
                                 SSWRITE_VALUE_QSTR,
                                 "maskParam1Name", 
                                 testTLCStr,
                                 SSWRITE_VALUE_STR,
                                 "maskParam2Name",
                                 maskParam2TLCName)) {
        return; /* An error occurred which will be reported by SL */
    }    
    ssWriteRTWStrParam(S,  "maskParam1NewTLCName", maskParam1TLCName);
}
Mask Parameter 1 is
'maskParam1TLCName' 
Mask Parameter 2 is
'maskParam2TLCName'
TLC CODE SNIPPET
%assign maskParam1TLCName   = SFcnParamSettings.maskParam1Name
%assign maskParam2TLCName   = SFcnParamSettings.maskParam2Name
testStringFromMaskFcn( (uint32_T*)&%<maskParam1TLCName>, 
                       (uint32_T*)&%<maskParam2TLCName> );
testStringFromMaskFcn( (uint32_T*)&%<maskParam1TLCName>, 
                       (uint32_T*)"%<maskParam1NewTLCName>");
AUTO GEN CODE SNIPPET
testStringFromMaskFcn( (uint32_T*)&maskParam1TLCName,
                       (uint32_T*)&);
testStringFromMaskFcn( (uint32_T*)"m",
                       (uint32_T*)&);

In the above ssWriteRTWParamSettings case only testTLCStr goes through in the form of a string to auto-gen code however maskParam1TLCName and maskParam2TLCName do not go through.

Also in case of ssWriteRTWStrParam only the first character of maskParam1TLCName goes through to auto-gen code
