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.
