STGETR - Gets the current value of an internal parameter of type REAL.

       To  use STGETR or c_stgetr, 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_stgetr(char *cnm, float *rvl)

       CNM         (CHARACTER,  input)  is the name of a parameter whose real value is to be retrieved. Only the
                   first three characters of CNM are examined. The three  characters  must  either  be  entirely
                   upper  or  entirely lower case; mixed case is not recognized. It is recommended that the rest
                   of the character string be used to improve the readability of the code. For example,  instead
                   of just ´ARL´, use ´ARL - Arrowhead Length´.

       RVL         (REAL,  output)  is  a variable in which the value of the parameter specified by CNM is to be
                   returned.

       CALL STGETR (CNM,RVL)

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