Each provide equivalent functionality to the respective memcpy() , memmove() , and memset() functions, except with differing parameters and return type in order to provide explicit runtime-constraints as defined in the C11 standard. Compiler Programming: Intrinsics for memcpy, memset, memcmp. Let's make sure you understand what some of the functions (like memset and memcpy) actually do before ever using them again!Jun 20, 2019 · While memcpy_s could be used inside an array, you may need to consider memmove instead (and the related memmove_s). There is a difference between moving some section from the end to the beginning of a block, vs moving, say, the last 2/3rds of a block to it's beginning.
