Concept of void pointer in C programming
...f the size of data type (e.g. pointer to 32-bit integer must be aligned at 4-byte boundary to be dereferenced).
For example, reading uint16_t from void*:
/* may receive wrong value if ptr is not 2-byte aligned */
uint16_t value = *(uint16_t*)ptr;
/* portable way of reading a little-endian value */...
