rpc(3N) rpc(3N)
If nettype is NULL, it defaults to
netpath. The transports are tried in left to right order in the NET-
PATH variable or in top to down order in the
/etc/netconfig file.
Derived Types
In a 64-bit environment, the derived types are defined as follows:
typedef unsigned long rpcprog_t;
typedef unsigned long rpcvers_t;
typedef unsigned long rpcproc_t;
typedef unsigned long rpcprot_t;
typedef unsigned long rpcport_t;
typedef int32_t rpc_inline_t;
In a 32-bit environment, the derived types are defined as follows:
typedef unsigned long rpcprog_t;
typedef unsigned long rpcvers_t;
typedef unsigned long rpcproc_t;
typedef unsigned long rpcprot_t;
typedef unsigned long rpcport_t;
typedef long rpc_inline_t;
Data Structures
Some of the data structures used by the RPC package are shown below.
The AUTH Structure
union des_block {
struct {
u_int32 high;
u_int32 low;
} key;
char c[8];
};
typedef union des_block des_block;
extern bool_t xdr_des_block();
/*
* Authentication info. Opaque to client.
*/
struct opaque_auth {
enum_t oa_flavor; /* flavor of auth */
caddr_t oa_base; /* address of more auth stuff */
u_int oa_length; /* not to exceed MAX_AUTH_BYTES */
};
/*
* Auth handle, interface to client side authenticators.
*/
typedef struct {
struct opaque_auth ah_cred;
struct opaque_auth ah_verf;
union des_block ah_key;
struct auth_ops {
void (*ah_nextverf)();
int (*ah_marshal)(); /* nextverf & serialize */
int (*ah_validate)(); /* validate verifier */
int (*ah_refresh)(); /* refresh credentials */
void (*ah_destroy)(); /* destroy this structure */
} *ah_ops;
caddr_t ah_private;
} AUTH;
The CLIENT Structure
/*
* Client rpc handle.
