NAME¶
VVGETR - Gets the current value of a Vectors parameter of type REAL.
SYNOPSIS¶
CALL VVGETR (CNM,RVL)
C-BINDING SYNOPSIS¶
#include <ncarg/ncargC.h>
void c_vvgetr(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 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 ´DMX´, use ´DMX - Device Maximum Vector
Size´.
- 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 Vectors parameters of
type REAL. For a complete list of parameters available in this utility, see
the vectors_params man page.
EXAMPLES¶
Use the ncargex command to see the following relevant examples: ffex02, ffex05,
vvex01, vvex02.
ACCESS¶
To use VVGETR or c_vvgetr, 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.
