TDGETR - Retrieves the real value of a Tdpack parameter.

       To  use TDGETR or c_tdgetr, 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_tdgetr (char *pnam, float *rval)

       The arguments of TDGETR are as follows:

       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 three 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 "tdpack" man page for a description of all Tdpack error messages and/or informational messages.
