RPC_GSS_MAX_DATA_LENGTH(3) BSD Library Functions Manual RPC_GSS_MAX_DATA_LENGTH(3)NAME
rpc_gss_max_data_length -- calculate maximum data size
LIBRARY
RPC GSS-API Authentication Library (librpcsec_gss, -lrpcsec_gss)
SYNOPSIS
#include <rpc/rpcsec_gss.h>
int
rpc_gss_max_data_length(AUTH *auth, int max_tp_unit_len);
DESCRIPTION
Calculate the maximum message size that will fit into a packet of size max_tp_unit_len, given the current service and QoP setting.
PARAMETERS
auth A handle to a RPCSEC_GSS security context
max_tp_unit_len Maximum packet size of the underlying transport protocol
RETURN VALUES
The maximum message size that can be encoded
SEE ALSO gssapi(3), rpc(3), rpcset_gss(3)HISTORY
The rpc_gss_max_data_length function first appeared in FreeBSD 8.0.

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.

Introduction
Originally, we only had one shell on unix. When ran a command, the shell would attempt to invoke one of the exec() system calls on it. It the command was an executable, the exec would succeed and the command would run. If the exec() failed, the shell would not give up, instead it... (3 Replies)

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)
