.TH GOPEN_GKS 3NCARG "March 1993" UNIX "NCAR GRAPHICS"
.SH NAME
gopen_gks \- opens the GKS package
.SH SYNOPSIS
#include <ncarg/gks.h>
.sp
void gopen_gks(const char *err_file, size_t mem_unit);
.SH DESCRIPTION
.IP err_file 12
(Input) \- The place to which error messages are to be written. 
Typically this should be "stdout".
.IP mem_unit 12
(Input) \- The dimension of an internal buffer. 
Currently in NCAR GKS-0A, mem_unit is ignored.
.SH USAGE
To get output to any workstation,
gopen_gks, gopen_ws and gactivate_ws must be called in that order.
For jobs producing only CGM output, the three calls to gopen_gks, gopen_ws,
and gactivate_ws 
can be replaced with a call to the SPPS function c_opngks().
.SH ACCESS
To use the GKS C-binding routines, load the ncarg_gks and
ncarg_c libraries.
