A macro that calls a remote procedure.
    Format
      #include  <rpc/rpc.h>
      enum clnt_stat  clnt_call(CLIENT *handle, u_long procnum,
                      xdrproc_t inproc, char *in, xdrproc_t outproc,
                      char *out, struct timeval timeout);

1  –  Arguments

 handle
    A pointer to a client handle created by any of the client-handle
    creation routines.
 procnum
    The procedure number associated with the remote procedure.
 inproc
    The XDR routine used to encode the remote procedure's arguments.
 in
    A pointer to the remote procedure's arguments.
 outproc
    The XDR routine used to decode the remote procedure's results.
 out
    A pointer to the remote procedure's results.
 timeout
    A structure describing the time allowed for results to return to
    the client. If you have previously used the clnt_control macro
    with the CLSET_TIMEOUT code, this value is ignored.

2  –  Description

    Use the clnt_call macro after using one of the client-handle
    creation routines. After you are finished with the handle, return
    it using the clnt_destroy macro. Use the clnt_perror to print any
    errors that occurred.

3  –  Return Values

    RPC_SUCCESS        Indicates success.
    clnt_stat          Returns the buffer of type enum clnt_stat
                       containing the status of the clnt_call
                       operation.
