MATLAB: How to avoid compilation error: expression must be a modifiable lvalue

lvaluemodifiablePolyspace Client for C/C++

Hi.
I met a compilation error with following code. a physical buffer (communication buffer of MCU) tossed to void* dest. if I change all argument to local variable and pointer compilation successful.
First I thought, polyspace doesn't understand typecasting of void to other, but I guess now when physical address is tossed as argument then it occur compilation error "expression must be a modifiable lvalue", since polyspace doesn't understand physical address.
Am i thinking correct? and does anybody can help me to avoid compilation error?
typedef unsigned char u08;
void* AL_MemCpy  (void* dest, const void* source, u08 count)
{
  while (count--)
  {
       *((u08*)dest)++ = *((u08*)source)++;
  }
}
// used in other function like below
(void)AL_MEMCPY(RxBuffer,&(data[1]),(u08)RxMessage.Length);

Best Answer

(u8 *) dest is a temporary variable, which cannot be increased. Perhaps you want this:
*((u08*)dest++) = *((u08*)source++);
But this copies the first byte only. Perhaps memcpy would be smarter?
Or:
u08 *d = (u08 *) dest, *s = (u08 *) source;
while (count--) {
  *d++ = *s++;
}
