ncl_isgetr man page

ISGETR — Gets the current values of internal parameters of type REAL.

Synopsis

CALL ISGETR (CNP,RVP)

C-Binding Synopsis

#include <ncarg/ncargC.h>

void c_isgetr (char *cnp, float *rvp)

Description

CNP
(an input expression of type CHARACTER) is the name of an internal parameter. Only the first two characters of the name are meaningful, but a longer character string may be used to more clearly document what internal parameter is being retrieved.
RVP
(an output variable of type REAL) is the name of a variable into which the value of the parameter specified by CNP is to be retrieved. If the internal parameter is inherently an integer value "i", "REAL(i)" will be returned as the value of RVP.

Usage

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

C-Binding Description

The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

Access

To use ISGETR or c_isgetr, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.

Messages

See the isosurface man page for a description of all Isosurface error messages and/or informational messages.
