NAME

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

SYNOPSIS

       CALL STGETR (CNM,RVL)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_stgetr(char *cnm, float *rvl)

DESCRIPTION

       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.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

USAGE

       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.

ACCESS

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

MESSAGES

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