MEMMOVE(3) Linux Programmer's Manual MEMMOVE(3)

memmove - copy memory area

#include <string.h>
void *memmove(void *dest, const void *src, size_t n);

The memmove() function copies n bytes from memory area src to memory area dest. The memory areas may overlap: copying takes place as though the bytes in src are first copied into a temporary array that does not overlap src or dest, and the bytes are then copied from the temporary array to dest.

The memmove() function returns a pointer to dest.

For an explanation of the terms used in this section, see attributes(7).
