NGGETR - Gets the current real value of an internal parameter of Ngmisc of type REAL. See the

       To  use  NGGETR  or  c_nggetr,  load  the NCAR Graphics libraries ncarg, ncarg_gks, ncarg_c, and ncarg_c,
       preferably in that order.

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

       #include <ncarg/ncargC.h>

       void c_nggetr (char *pnam, float *rval)

       PNAM        (an  input  constant or variable of type CHARACTER) specifies the name of the parameter whose
                   value is to be retrieved. Only the first two characters of the string are examined.

       RVAL        (an output variable of type REAL) is the value of the internal parameter.

       NGGETR - Gets the current real value of an internal parameter of Ngmisc of type REAL.  See the
       ngmisc_params man page for a complete list of all the Ngmisc internal parameters.

       This routine allows you to retrieve the current value of Ngmisc  parameters.   For  a  complete  list  of
       parameters available in this utility, see the ngmisc_params man page.
