ISGETR - Gets the current values of internal parameters of type REAL.

       To use ISGETR or c_isgetr, 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_isgetr (char *cnp, float *rvp)

       CNP         (an  input expression of type CHARACTER) is the name of an internal parameter. Only the first
                   two characters of the name are meaningful, but a longer character string may be used to  more
                   clearly document what internal parameter is being retrieved.

       RVP         (an  output  variable  of  type  REAL)  is the name of a variable into which the value of the
                   parameter specified by CNP is to be retrieved.  If the internal parameter  is  inherently  an
                   integer value "i", "REAL(i)" will be returned as the value of RVP.

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

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