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.
