NAME
     inet_cidr_ntop, inet_cidr_pton - network translation routines

SYNOPSIS
     #include <sys/types.h>
     #include <sys/socket.h>
     #include <netinet/in.h>
     #include <arpa/inet.h>

     inet_cidr_ntop(___ __, _____ ____ ____, ___ ____, ____ ____, ______ ____)

     inet_cidr_pton(___ __, _____ ____ ____, ____ ____, ___ _____)

DESCRIPTION
     These routines are used for converting addresses to and from network and
     presentation forms with CIDR (Classless Inter-Domain Routing) representa-
     tion, embedded net mask.

                     130.155.16.1/20

     inet_cidr_ntop() converts an address from network to presentation format.

     __ describes the type of address that is being passed in ____  Currently
     only AF_INET is supported.

     ___ is an address in network byte order, its length is determined from
     ___

     ____ specifies the number of bits in the netmask unless it is -1 in which
     case the CIDR representation is omitted.

     ___ is a caller supplied buffer of at least ____ bytes.

     inet_cidr_ntop() returns ___ on success or NULL.  Check errno for reason.

     inet_cidr_pton() converts and address from presentation format, with op-
     tional CIDR reperesentation, to network format.  The resulting address is
     zero filled if there were insufficint bits in ____

     __ describes the type of address that is being passed in via ___ and de-
     termines the size of ____

     ___ is an address in presentation format.

     ____ returns the number of bits in the netmask or -1 if a CIDR represen-
     tation was not supplied.

     inet_cidr_pton() returns 0 on succces or -1 on error.  Check errno for
     reason.  ENOENT indicates an invalid netmask.
