 RPC_GSS_MAX_DATA_LENGTH 3NSL "Feb 5, 2002"
 NAME
rpc_gss_max_data_length, rpc_gss_svc_max_data_length - get maximum data length
for transmission

 SYNOPSIS


#include <rpc/rpcsec_gss.h>

int rpc_gss_max_data_length(AUTH *handle, int max_tp_unit_len);






int rpc_gss_svc_max_data_length(struct svc_req *req, int max_tp_unit_len);




 DESCRIPTION

Performing a security transformation on a piece of data generally produces
data with a different (usually greater) length. For some transports, such as
UDP, there is a maximum 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.


rpc_gss_max_data_length() is the client-side version;
rpc_gss_svc_max_data_length() is the server-side version.

 PARAMETERS
handle 


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



max_tp_unit_len 


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



req 


A pointer to an RPC svc_req structure, containing information on the
context (for example, program number and credentials).




 RETURN VALUES

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