NGGETR — Gets the current real value of an internal parameter of Ngmisc of type REAL. See the ngmisc_params man page for a complete list of all the Ngmisc internal parameters.

Synopsis

CALL NGGETR (PNAM, RVAL)

C-Binding Synopsis

#include <ncarg/ncargC.h>

void c_nggetr (char *pnam, float *rval)

Description

PNAM
(an input constant or variable of type CHARACTER) specifies the name of the parameter whose value is to be retrieved. Only the first two characters of the string are examined.
RVAL
(an output variable of type REAL) is the value of the internal parameter.

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 Ngmisc parameters. For a complete list of parameters available in this utility, see the ngmisc_params man page.

Access

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