MEMCPY(3)                 NetBSD Programmer's Manual                 MEMCPY(3)


NAME

     memcpy - copy byte string


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <string.h>

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


DESCRIPTION

     The memcpy() function copies len bytes from string src to string dst.
     The arguments must not overlap -- behavior if the arguments overlap is
     undefined. To copy byte strings that overlap, use memmove(3).


RETURN VALUES

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


SEE ALSO

     bcopy(3), memccpy(3), memmove(3), strcpy(3)


STANDARDS

     The memcpy() function conforms to ISO/IEC 9899:1999 (``ISO C99'').
