Set stored integer value for 32-bit region of real, scalar signal element
extern ssFxpSetU32BitRegion(SimStruct *S, void *pVoid DTypeId dataTypeId uint32 regionValue 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.
Stored integer value that you want to assign to a 32-bit region.
Index of the 32-bit region whose stored integer value you want to set, where 0 accesses the least significant 32-bit region.
This function sets
regionValue as the stored
integer value of the 32-bit region specified by
associated with the fixed-point data type designated by
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, ensure that the remaining bits are sign extended.
This function generates an error if
a floating-point data type, or if the stored integer value that you
set is invalid.
