HISTORY
     A bzero() function appeared in 4.3BSD.  Its prototype existed previously in <string.h> before it was moved to <strings.h> for IEEE Std
     1003.1-2001 (``POSIX.1'') compliance.

     bzero() was deprecated in IEEE Std 1003.1-2001 (``POSIX.1'') and removed in IEEE Std 1003.1-2008 (``POSIX.1'').
