Purpose
Installs the network name of the caller in the array specified by the name parameter.
Library
C Library (libc.a)
Syntax
#include <rpc/rpc.h>getnetname ( name)
char name [MAXNETNAMELEN];
Description
The getnetname subroutine installs the caller's unique, operating-system-independent network name in the fixed-length array specified by the name parameter.
Parameters
| Item | Description |
|---|---|
| name | Specifies the network name (or netname) of the server process owner. The name parameter can be either the host name derived from the host2netname subroutine or the user name derived from the user2netname subroutine. |
Return Values
Upon successful completion, this subroutine returns a value of 1. If unsuccessful, it returns a value of 0.
Purpose
Generates the operating-system-independent network name of the caller.
Library
Network Services Library (libnsl.a)
Syntax
#include <rpc/rpc.h>getnetname ( name)
char *name;Description
The getnetname subroutine, which belongs to the secure RPC category, is used in applications that use the AUTH_DES authentication flavor. This subroutine generates the network name (or netname) of the caller. If the caller has root authority, the net name of the host machine is generated.
Parameters
| Item | Description |
|---|---|
| name | Represents the network name of the caller. |
Return Values
| Item | Description |
|---|---|
| 1 | successful |
| 0 | unsuccessful |
Examples
#include <rpc/rpc.h>
int main()
{
char name[255]; /* contains netname of owner of server process */
char rhost[255]; /* Remote host name on which server resides */
rpcprog_t PROGNUM = 0x3fffffffL;
rpcvers_t PROGVER = 0x1L;
if(!getnetname(name))
{
fprintf(stderr,"getnetname() error\n");
exit(1);
}
/* Create a client handle for remote host rhost for PROGNUM & PROGVER on tcp transport */
clnt = clnt_create(rhost, PROGNUM, PROGVER, "tcp");
if (clnt == (CLIENT *) NULL) {
fprintf(stderr,"client_create() error\n");
exit(1);
}
clnt->cl_auth = authdes_seccreate(name, 80, rhost, (des_block *)NULL);
/*
* Make a call to clnt_call() subroutine
*/
/* Destroy the authentication handle */
auth_destroy(clnt->cl_auth);
/* Destroy the client handle in the end */
clnt_destroy(clnt);
return 0;
