ncl_gagetr man page

GAGETR — Retrieves the real value of an internal parameter of Gridall.

Synopsis

CALL GAGETR (PNAM,RVAL)

C-Binding Synopsis

#include <ncarg/ncargC.h>

void c_gagetr (char *pnam, float *rval)

Description

PNAM
(an input constant or variable of type CHARACTER) is a string three or more characters in length, the first three characters of which constitute the name of the internal parameter whose value is to be retrieved.
RVAL
(an output variable of type REAL) is the name of a variable into which the value of the internal parameter specified by PNAM is to be retrieved. If the internal parameter is of type INTEGER and has the value "i", "REAL(i)" will be returned in RVAL.

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

Access

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

Messages

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