Return stored integer value for 32-bit region of real, scalar signal element
extern uint32 ssFxpGetU32BitRegion(SimStruct *S, const void *pVoid DTypeId dataTypeId unsigned int regionIndex)
SimStruct representing an S-function block.
Pointer to the storage container of the real, scalar signal element in which the 32-bit region of interest resides.
Data type ID of the registered data type corresponding to the signal.
Index of the 32-bit region whose stored integer value you want to retrieve, where 0 accesses the least significant 32-bit region.
This function returns the stored integer value in the 32-bit region specified by regionIndex, associated with the fixed-point data type designated by dataTypeId. You can use this function with any fixed-point data type, including those with word sizes less than 32 bits. If the fixed-point word size is less than 32 bits, the remaining bits are sign extended.
This function generates an error if dataTypeId represents a floating-point data type.
To use this function, you must include fixedpoint.h and fixedpoint.c. For more information, see Structure of the S-Function.
