VVGETR(3NCARG) | NCAR GRAPHICS | VVGETR(3NCARG) |
VVGETR - Gets the current value of a Vectors parameter of type REAL.
CALL VVGETR (CNM,RVL)
#include <ncarg/ncargC.h>
void c_vvgetr(char *cnm, float *rvl)
The C-binding argument descriptions are the same as the FORTRAN argument descriptions.
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.
Use the ncargex command to see the following relevant examples: ffex02, ffex05, vvex01, vvex02.
To use VVGETR or c_vvgetr, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
See the vectors man page for a description of all Vectors error messages and/or informational messages.
