BCOPY(3)                NetBSD Library Functions Manual               BCOPY(3)


NAME

     bcopy -- copy byte string


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <strings.h>

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


DESCRIPTION

     The bcopy() function copies len bytes from string src to string dst.  The
     two strings may overlap.  If len is zero, no bytes are copied.

     This function is obsolete.  The functions memcpy(3) and/or memmove(3)
     should be used instead.  Note that bcopy() takes its src and dst argu-
     ments in the opposite order from these.


SEE ALSO

     memccpy(3), memcpy(3), memmove(3), strcpy(3), strncpy(3)


STANDARDS

     The bcopy() function conforms to IEEE Std 1003.1-2001 (``POSIX.1'').  The
     IEEE Std 1003.1-2004 (``POSIX.1'') revision marked it as legacy; the IEEE
     Std 1003.1-2008 (``POSIX.1'') revision removed it from the specification.

     A bcopy() function appeared in 4.2BSD.
