Hi,
I have a issue with owfs and can't figure out what to do. I created an
raspberry pi 2 process that runs on startup and collects data from 1-wire
network. What happened is that process just stops at some point. Scratching
my head why and after a couple of days, figured out that my process "eats"
more and more memory so looks like, in some point, it just terminates.
After eliminating all I ended up with only this:
#include <stdio.h>
#include <stdlib.h>
#include <owcapi.h>
#include <assert.h>
#include <signal.h>
#include <pthread.h>
volatile sig_atomic_t stop;
void inthand(int signum) {
stop = 1;
}
void *repeating_fnc(void *var){
char *buf;
size_t s;
int i;
char** tokens;
while (!stop){
OW_get("/",&buf,&s);
}
}
int main(int argc, char **argv)
{
signal(SIGINT, inthand);
OW_init("--usb=all");
pthread_t inc_thread;
int dummy=0;
if(pthread_create(&inc_thread, NULL, repeating_fnc, &dummy)) {
fprintf(stderr, "Error creating thread\n");
return 1;
}
while(!stop);
if(pthread_join(inc_thread, NULL)) {
fprintf(stderr, "Error joining thread\n");
return 2;
}
printf("exiting\n");
OW_finish();
return 0;
} // main
and this also consumes memory like crazy (i used top to see that and %MEM
goes by 0.1% up every 10 to 15 seconds! Also VIRT and RES are going up: RES
a little faster than VIRT). I am using Dallas Semiconductor DS1490F 2-in-1
Fob, 1-Wire adapter as USB to 1-wire. Owfs is version 3.1p1.
What might be the cause of this behavior? What can I do to solve this
problem?
Kind regards,
Gabrijel
