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

       To  use PCGETR or c_pcgetr, 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_pcgetr (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 two characters of the string. If the internal parameter  is  one  of
                   the  two  (´BC´ and ´CC´) that are arrays, the index of the desired array element may appear,
                   enclosed in parentheses, in columns 3 and following. Other characters may be used to document
                   the use of the parameter being retrieved; for example, instead of just ´MA´, one can use  ´MA
                   - MAPPING FLAG´ and, instead of ´CC(10)´, one can use ´CC(10) - SPECIAL COLOR 10´.

       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)".

       Use the ncargex command to see the following relevant examples: cpexcc, epltch, vvexcc, fpchiqu.
