nng_dialer_id - return numeric dialer identifier

       The nng_dialer_id() function returns a positive identifier for the dialer d, if it is valid. Otherwise it
       returns -1.

           Note

           A dialer is considered valid if it was ever created with the nng_dialer_create() or nng_dial()
           functions. Dialers that are allocated on the stack or statically should be initialized with the macro
           NNG_DIALER_INITIALIZER to ensure that they cannot be confused with a valid dialer before they are
           created properly.

       None.
