NAME

       rpc_gss_max_data_length(), rpc_gss_svc_max_data_length() - get maximum data length for transmission

SYNOPSIS


DESCRIPTION

       Performing a security transformation on a piece of data generally produces 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.  You can use the following two
       functions to determine the maximum data length for transmission.  is the client-side version, and is the server-side version.

PARAMETERS

       The following parameters can be used with these functions:

       handle	 An RPC context handle of type returned when a context is created (for example, by Security service and QOP are bound to this han-
		 dle, 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 structure, containing information on the context (for example, program number and credentials).

MULTITHREAD USAGE

       Thread Safe:	     Yes
       Cancel Safe:	     Yes
       Fork Safe:	     No
       Async-cancel Safe:    No
       Async-signal Safe:    No

       These  functions can be called safely in a multithreaded environment.  They may be cancellation points in that they call functions that are
       cancel points.

       In a multithreaded environment, these functions are not safe to be called by a child process after and before These functions should not be
       called by a multithreaded application that supports asynchronous cancellation or asynchronous signals.

RETURN VALUE

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

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().  Secu-
			       rity 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 cre-
			       dentials).

RETURN VALUES

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