IDGETR - Retrieves the real value of a Bivar parameter.

       To  use IDGETR or c_idgetr, load the NCAR Graphics libraries ncarg, ncarg_gks, 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_idgetr (char *pnam, float *rval)

       PNAM        (an  input  constant or variable of type CHARACTER) - The name of the parameter that you want
                   to retrieve.  The character string can be of any length, but only the first two characters of
                   it will be examined.

       RVAL        (an output variable of type REAL) - A real variable to receive the desired  parameter  value.
                   If the internal parameter is of type REAL and has the value "r", RVAL will be given the value
                   "r";  if  the internal parameter is of type INTEGER and has the value "i", RVAL will be given
                   the value "REAL(i)".

       See the bivar man page for a description of all Bivar error messages and/or informational messages.

       CALL IDGETR (PNAM,RVAL)

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