Copy between arrays with different element size in C -

i need copy elements uint8_t array float array.

i wrote simple function came mind instantly.

float *uint8_t_mas_to_float_mas(uint8_t *src, int size) {     float *dst = null;     if (!src)         return null;      dst = (float*)calloc(size, sizeof(float));      if (!dst)         return null;      (int = 0; < size; i++)         dst[i] = (float)src[i];      return dst; } 

but think it's not effective , unfortunatelly cant come else.

can help?

thank you.

you should write (equivalent):

float *uint8_t_mas_to_float_mas(uint8_t *src, int size) {     if (!src)         return null;      float *dst = (float*)malloc(size*sizeof(float));      if (!dst)         return null;      (int = 0; < size; i++)         dst[i] = (float)src[i];      return dst; } 

this ok. let optimizer it's job. bottleneck malloc call - don't need here, unless copying millions of elements.
