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 */
ss2sss(50.0); /* Fast spinning! */
if (lkc != *kc) { /* Space bar pressed? */
if (drand48() > 0.5) ss2sas(1); /* Random auto spin state */
else ss2sas(0);
}
float qas = ss2qas(); /* Query autospin state */
char string[32];
if (qas == 0)
sprintf(string,"Not spinning"); /* Write to string */
else
sprintf(string,"Whee...."); /* Write to string */
s2textxy(0,0,0,string); /* Display text */
lkc = *kc; /* Update count */
}
int main(int argc, char *argv[])
{
fprintf(stderr,"Press <spacebar> to randomly change autospin state \n");
s2opend("/s2mono",argc, argv); /* Open the display: mono */
s2swin(-1.,1., -1.,1., -1.,1.); /* Set the window coordinates */
cs2scb(cb); /* Install dynamic callback */
s2show(1); /* Open the s2plot window */
return 1;
}
