Web18 mrt. 2016 · Quite often people find it confusing that memcpy returns the destination buffer pointer, because there is a popular belief that returning a pointer form a function should normally (or always) indicate that the function might allocate/reallocate memory. Web18 jan. 2010 · Thank You. Jan 18, 2010 at 4:40am. somshekhar (33) hi Katty, You have declared the variable as uint8_t which is unsigned char and takes 1 byte of memory and uint32_t is unsigned int and takes 4 bytes of memory. So when you assign as headd.c = 4, it cannot accomodate the data with in, correct?
