ПРЕДИСЛОВИЕ

       This manual page is part of the POSIX Programmer's Manual.  The

       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

НАЗВАНИЕ

       memmove — copy bytes in memory with overlapping areas

СИНТАКСИС

       #include <string.h>

       void *memmove(void *s1, const void *s2, size_t n);

ОПИСАНИЕ

       The functionality described on this reference page is aligned
       with the ISO C standard. Any conflict between the requirements
       described here and the ISO C standard is unintentional. This
       volume of POSIX.1‐2017 defers to the ISO C standard.

       The memmove() function shall copy n bytes from the object pointed
       to by s2 into the object pointed to by s1.  Copying takes place
       as if the n bytes from the object pointed to by s2 are first
       copied into a temporary array of n bytes that does not overlap
       the objects pointed to by s1 and s2, and then the n bytes from
       the temporary array are copied into the object pointed to by s1.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       The memmove() function shall return s1; no return value is
       reserved to indicate an error.
