ncl_stgetr man page

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.
