NAMErpc_clnt_auth: auth_destroy(), authnone_create(), authsys_create(), authsys_create_default() — library routines for client side remote procedure call authentication SYNOPSIS#include <rpc/rpc.h> void auth_destroy(AUTH *auth); AUTH *authnone_create(void); AUTH *authsys_create( const char *host, const uid_t uid, const gid_t gid, const int len, const gid_t *aup_gids); AUTH *authsys_create_default(void); DESCRIPTIONThese routines are part of the RPC library that allows C language programs to make procedure calls on other machines across the network, with desired authentication. These routines are normally called after creating the CLIENT handle. The cl_auth field of the CLIENT structure should be initialized by the AUTH structure returned by some of the following routines. The client's authentication information is passed to the server when the RPC call is made. Only the NULL and the SYS style of authentication is discussed here. For the DES style authentication, please refer to secure_rpc(3N). The NULL and SYS style of authentication are safe in multithreaded applications. The HP-UX implementation of RPC only supports the X/Open Transport Interface (XTI). Applications that are written using the Transport Layer Interface (TLI) and wish to use RPC, must convert their application to XTI. RoutinesThe following routines require that the header <rpc/rpc.h> be included (see rpc(3N) for the definition of the AUTH data structure).
MULTITHREAD USAGE
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 fork() and before exec(). These functions should not be called by a multithreaded application that supports asynchronous cancellation or asynchronous signals. |
