#include <rpc/rpcsec_gss.h>int rpc_gss_max_data_length(AUTH *handle, int max_tp_unit_len);
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.
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.
The maximum size of a piece of data allowed by the transport.
A pointer to an RPC svc_req structure, containing information on the context (for example, program number and credentials).
Both functions return the maximum size of untransformed data allowed, as an int .
