ncl_vvgeti man page

VVGETI — Gets the current value of a Vectors parameter of type INTEGER.

Synopsis

CALL VVGETI (CNM,IVL)

C-Binding Synopsis

#include <ncarg/ncargC.h>

void c_vvgeti(char *cnm, int *ivl)

Description

CNM
(CHARACTER, input) is the name of a parameter whose integer value is to be retrieved. Only the first three characters of CNM are examined. The three characters may 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 ´PLR´, use ´PLR - Polar Input Mode´.
IVL
(INTEGER, 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 Vectors parameters of type INTEGER. For a complete list of parameters available in this utility, see the vectors_params man page.

Access

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

Messages

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