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 *dst, const void *src, size_t len);


DESCRIPTION

     The memcpy() function copies len bytes from string src to string dst.


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 ANSI X3.159-1989 (``ANSI C'').


BUGS

     In this implementation memcpy() is implemented using bcopy(3), and there-
     fore the strings may overlap.  On other systems, copying overlapping
     strings may produce surprises.  A simpler solution is to not use
     memcpy().
