DPGETR - Retrieves the real value of an internal parameter of type REAL or INTEGER.

       To use DPGETR or c_dpgetr, 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_dpgetr (char *pnam, float *rval)

       PNAM        (an  input expression of type CHARACTER) specifies the name of the parameter to get. The name
                   must appear as the first three characters of the string.  Other characters  may  be  used  to
                   document  the  use  of the parameter being retrieved; for example, instead of just ´LS1´, one
                   can use ´LS1 - LABEL SPACING PARAMETER 1´.

       RVAL        (an output variable of type REAL) is the name of the variable into which  the  value  of  the
                   internal  parameter  specified  by  PNAM  is to be retrieved.  If the internal parameter is a
                   value "r" of type REAL, the value returned is "r".  If the internal parameter is a value  "i"
                   of type INTEGER, the value returned is "REAL(i)".
