memmove - copy memory area
Standard C library (libc
, -lc
)
#include <string.h>
void *memmove(void dest[.n], const void src[.n], 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
.
