pmap_rmtcall()

The pmap_rmtcall() call instructs Portmapper to make an RPC call to a procedure on a host on your behalf. Use this procedure only for ping-type functions.

Syntax

#include <rpc\rpc.h>
#include <netdb.h>

enum clnt_stat
pmap_rmtcall(addr, prognum, versnum, procnum , inproc, in,
             outproc, out, tout, portp)
struct sockaddr_in *addr;
u_long prognum;
u_long versnum;
u_long procnum;
xdrproc_t inproc;
char *in;
xdrproc_t outproc;
char *out;
struct timeval tout;
u_long *portp;

Parameters

addr

Pointer to the internet address of the foreign host. prognum

Remote program number. versnum

Version number of the remote program. procnum

Procedure to be called. inproc

XDR procedure that encodes the arguments of the remote procedure. in

Pointer to the arguments of the remote procedure. outproc

XDR procedure that decodes the results of the remote procedure. out

Pointer to the results of the remote procedure. tout

Time-out period for the remote request. portp

prognum

versnum

procnum

Return Values

RPC_SUCCESS indicates success; otherwise, an error has occurred. The results of the remote procedure call return to out.

Examples

int inproc, outproc,rc;u_long portp;
struct timeval total_timeout;
struct sockaddr_in *addr;
...
get_myaddress(addr);
...
total_timeout.tv_sec = 20;
total_timeout.tv_usec = 0;

rc = pmap_rmtcall(addr,RMTPROGNUM,RMTPROGVER,RMTPROCNUM,xdr_int,
&inproc,xdr_int,&outproc,total_timeout,&portp);
if (rc != 0)
 {
  fprintf(stderr,"error: pmap_rmtcall() failed: %d \n",rc);
  clnt_perrno(rc);
  exit(1);
 }
