Detailed Description
Function Documentation
   KRB5_LIB_FUNCTION krb5_error_code KRB5_LIB_CALL krb5_addr2sockaddr (krb5_con-
     text   context,   const   krb5_address   *  addr,	struct	sockaddr  *  sa,
     krb5_socklen_t * sa_size, int port)
     krb5_addr2sockaddr sets the 'struct sockaddr sockaddr' from addr and  port.
     The  argument sa_size should initially contain the size of the sa and after
     the call, it will contain the actual length of the address. In case of  the
     sa  is  too  small  to  fit  the  whole address, the up to *sa_size will be
     stored, and then *sa_size will be set to the required length.

     Parameters
	 context a Keberos context
	 addr the address to copy the from
	 sa the struct sockaddr that will be filled in
	 sa_size pointer to length of sa, and after the call,  it  will  contain
	 the actual length of the address.
	 port set port in sa.

     Returns
	 Return  an  error code or 0. Will return KRB5_PROG_ATYPE_NOSUPP in case
	 address type is not supported.

     Returns
	 Return an TRUE is the address are the same FALSE if not

   KRB5_LIB_FUNCTION int KRB5_LIB_CALL krb5_address_order (krb5_context context,
     const krb5_address * addr1, const krb5_address * addr2)

     used for sorting addresses. If the addresses are the same address	krb5_ad-
     dress_order will return 0. Behavies like memcmp(2).

     Parameters
	 context a Keberos context
	 addr1 krb5_address to compare
	 addr2 krb5_address to compare

     Returns
	 <  0 if address addr1 in 'less' then addr2. 0 if addr1 and addr2 is the

     Calculate	the boundary addresses of `inaddr'/`prefixlen' and store them in
     `low' and `high'.

     Parameters
