NAME
     rpcgssmaxdatalength, rpcgsssvcmaxdatalength  -  get
     maximum data length for  transmission

SYNOPSIS
     #include 

     int rpcgssmaxdatalength(AUTH *handle, int maxtpunitlen);


     int rpcgsssvcmaxdatalength(struct svcreq *req, int maxtpunitlen);


DESCRIPTION
     Performing a security transformation on a piece of data gen-
     erally  produces   data  with  a different (usually greater)
     length.  For some transports, such as UDP, there is  a  max-
     imum  length of data which can be sent out in one data unit.
     Applications need to know the maximum size a piece  of  data
     can  be  before it's transformed, so that the resulting data
     will still "fit"  on  the  transport.  These  two  functions
     return that maximum size.


     rpcgssmaxdatalength()  is   the   client-side   version;
     rpcgsssvcmaxdatalength() is the server-side version.

PARAMETERS
     handle              An RPC  context  handle  of  type  AUTH,
                         returned  when a context is created (for
                         example, by  rpcgssseccreate().  Secu-
                         rity  service  and QOP are bound to this
                         handle, eliminating any need to  specify
                         them.


     maxtpunitlen     The maximum size  of  a  piece  of  data
                         allowed by the transport.


     req                 A pointer to an RPC  svcreq  structure,
                         containing  information  on  the context
                         (for example, program number and creden-
                         tials).


RETURN VALUES
     Both functions return the maximum size of untransformed data
     allowed, as an int.
