SFLUSH - Flushes polylines, accumulated through calls to the routines PLOTIF and PLOTIT, from the SPPS

       To use SFLUSH or c_sflush, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in
       that order.

       #include <ncarg/ncargC.h>

       void c_sflush()

       common system routine.
