ncl_slgetr man page

SLGETR — Gets the current real value of an internal parameter of Scrolled_title of type INTEGER or REAL. See the scrolled_title_params man page for a complete list of all the Scrolled_title internal parameters.

Synopsis

CALL SLGETR (PNAM, RVAL)

C-Binding Synopsis

#include <ncarg/ncargC.h>

void c_slgetr (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 three characters of the string are examined.
RVAL
(an output variable of type REAL) is the value of the internal parameter. If the internal parameter is of type INTEGER and has the value "i", RVAL = REAL(i). If the internal parameter is of type REAL and has the value "r", RVAL = r.

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

Access

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

Messages

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