MEMCPY(3)                BSD Library Functions Manual                MEMCPY(3)

NAME
     memcpy -- copy memory area

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <string.h>

     void *
     memcpy(void *restrict dst, const void *restrict src, size_t n);

DESCRIPTION
     The memcpy() function copies n bytes from memory area src to memory area
     dst.  If dst and src overlap, behavior is undefined.  Applications in
     which dst and src might overlap should use memmove(3) instead.

RETURN VALUES
     The memcpy() function returns the original value of dst.

SEE ALSO
     bcopy(3), memccpy(3), memmove(3), strcpy(3), wmemcpy(3)

STANDARDS
     The memcpy() function conforms to ISO/IEC 9899:1990 (``ISO C90'').
