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).
