Prototype
int ss2qsr(void);
Description

Code Example
#include <stdio.h>
#include <stdlib.h>
#include "s2plot.h"
void cb(double *t, int *kc)
{
static int lkc = 0; /* Count of key presses */
if (lkc != *kc) { /* Space bar pressed? */
ss2ssr((int)(drand48()*94+5));
}
int qsr = ss2qsr(); /* Query sphere resolution */
char string[32];
sprintf(string,"Resolution = %d",qsr); /* Write to string */
s2textxy(0,-0.5,0,string); /* Display text */
ns2sphere(0,0.5,0,0.3,1,1,0); /* A yellow sphere */
lkc = *kc; /* Update count */
}
int main(int argc, char *argv[])
{
fprintf(stderr,"Press the <spacebar> to change sphere resolution");
s2opend("/s2mono", argc, argv); /* Open in mono mode */
s2swin(-1.,1., -1.,1., -1.,1.); /* Set the window coordinates */
s2box("BCDET",0,0,"BCDET",0,0,"BCDET",0,0); /* Draw coordinate box */
cs2scb(cb); /* Install dynamic callback */
s2show(1); /* Open the s2plot window */
return 1;
}
