NAME

6       VVGETR - Gets the current value of a Vectors parameter of type REAL.
7

SYNOPSIS

9       CALL VVGETR (CNM,RVL)
10

C-BINDING SYNOPSIS

12       #include <ncarg/ncargC.h>

14       void c_vvgetr(char *cnm, float *rvl)

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 may 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 ´DMX´, use ´DMX - Device
24                   Maximum Vector Size´.
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 Vectors
35       parameters of type REAL.  For a complete list of parameters available
36       in this utility, see the vectors_params man page.
37

EXAMPLES

39       Use the ncargex command to see the following relevant examples: ffex02,
40       ffex05, vvex01, vvex02.
41

ACCESS

43       To use VVGETR or c_vvgetr, load the NCAR Graphics libraries ncarg,
44       ncarg_gks, and ncarg_c, preferably in that order.
45

MESSAGES

47       See the vectors man page for a description of all Vectors error
48       messages and/or informational messages.
