NAME    [Toc]    [Back]

     memcpy -- copy byte string

LIBRARY    [Toc]    [Back]

     Standard C Library (libc, -lc)

SYNOPSIS    [Toc]    [Back]

     #include <string.h>

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

DESCRIPTION    [Toc]    [Back]

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

RETURN VALUES    [Toc]    [Back]

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

SEE ALSO    [Toc]    [Back]

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

STANDARDS    [Toc]    [Back]

     The memcpy() function conforms to ISO/IEC 9899:1990 (``ISO C89'').

BUGS    [Toc]    [Back]

     In this implementation memcpy() is implemented using bcopy(3), and therefore
 the strings may overlap.  On other systems, copying overlapping
     strings may produce surprises.  Programs intended to be portable should
     use memmove(3) when src and dst may overlap.
