Determine whether S-function is compliant with the U32 bit region interface
extern ssFxpSGetU32BitRegionCompliant(SimStruct *S, int *result)
This function checks whether the S-function calls ssFxpSetU32BitRegionCompliant to declare compliance with the memory footprint for fixed-point data types with 33 or more bits. Before calling any other Fixed-Point Designer™ API function on data with 33 or more bits, you must call ssFxpSetU32BitRegionCompliant as follows:
Note: The Fixed-Point Designer software assumes that S-functions that use fixed-point data types with 33 or more bits without calling ssFxpSetU32BitRegionCompliant are using the obsolete memory footprint that existed until R2007b. Either redesign these S-functions or isolate them using the library fixpt_legacy_sfun_support.
To use this function, you must include fixedpoint.h and fixedpoint.c. For more information, see Structure of the S-Function.
