NAME

6       STGETR - Gets the current value of an internal parameter of type REAL.
7

SYNOPSIS

9       CALL STGETR (CNM,RVL)
10

C-BINDING SYNOPSIS

12       #include <ncarg/ncargC.h>

14       void c_stgetr(char *cnm, float *rvl)
15

DESCRIPTION

17       CNM         (CHARACTER, input) is the name of a parameter whose real
18                   value is to be retrieved. Only the first three characters
19                   of CNM are examined. The three characters must either be
20                   entirely upper or entirely lower case; mixed case is not
21                   recognized. It is recommended that the rest of the
22                   character string be used to improve the readability of the
23                   code. For example, instead of just ´ARL´, use ´ARL -
24                   Arrowhead Length´.
25
26       RVL         (REAL, output) is a variable in which the value of the
27                   parameter specified by CNM is to be returned.
28

C-BINDING DESCRIPTION

30       The C-binding argument descriptions are the same as the FORTRAN
31       argument descriptions.
32

USAGE

34       This routine allows you to retrieve the current value of Streamlines
35       parameters of type REAL. For a complete list of parameters available in
36       this utility, see the streamlines_params man page.
37

ACCESS

39       To use STGETR or c_stgetr, load the NCAR Graphics libraries ncarg,
40       ncarg_gks, and ncarg_c, preferably in that order.
41

MESSAGES

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