VVGETC(3NCARG) NCAR GRAPHICS VVGETC(3NCARG)

NAME

VVGETC - Gets the current value of a Vectors parameter of type CHARACTER.

SYNOPSIS

CALL VVGETC (CNM,CVL)

C-BINDING SYNOPSIS

#include <ncarg/ncargC.h>

void c_vvgetc(char *cnm, char *cvl, int len)

DESCRIPTION

(CHARACTER, input) is the name of a parameter whose character 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 ´MXT´, use ´MXT - Maximum Vector Text String´.
(CHARACTER, 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 with the following exception:

The size of cvl as dimensioned in the calling program.

USAGE

This routine allows you to retrieve the current value of Vectors parameters of type CHARACTER. For a complete list of parameters available in this utility, see the vectors_params man page.

ACCESS

To use VVGETC or c_vvgetc, 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.
