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

NAME

     memmove - copy memory area

SYNOPSIS

     #include <string.h>

     void *memmove(void *dest, const void *src, size_t n);

DESCRIPTION

     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.

RETURN VALUE

     The memmove() function returns a pointer to dest.
