memmove is a function in the C standard library string.h that copies a block of memory of a given number of bytes to another location. Unlike memcpy, it is guaranteed to work correctly even when the source and destination regions overlap, so it can be used safely to shift elements forward or backward by one position within an array. When the regions do not overlap, memcpy may be faster.
