From the rpc_clnt_create(3nsl) man page:

     struct rpc_createerr rpc_createerr

...

     These routines are MT-Safe. In  the  case  of  multithreaded
     applications,  the  -mt option must be specified on the com-
     mand line at compilation  time.   When  the  -mt  option  is
     specified, rpc_createerr() becomes a macro that enables each
     thread to have its own rpc_createerr(). See threads(5).

...

     rpc_createerr()

         A global variable whose value is set by any  RPC  client
         handle  creation  routine that fails.  It is used by the
         routine clnt_pcreateerror() to print the reason for  the
         failure.

Since rpc_createerr is a global variable, there shouldn't be parens (three times above). In addition, as a minor nit, semicolon should be placed after the rpc_createerr declaration in the man page synopsis.
