rpc_gss_max_data_lengNetworking Services Library rpc_gss_max_data_length(3NSL)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 pro‐
duces data with a different (usually greater) length. For some trans‐
ports, 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, contain‐
ing 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.
