send and recv event between processes with very few lines of code

kbz-event

Send and recv event between processes/threads in very few lines of codes.

• Unlimited buffer size
• WITHOUT any initialization or daemon process.
• Fast and simple

Usage:

server.c

#include <kbz-event.h>

void main() {
  
  for (;;) {
    char *buf;
    int len;
    
    // wait event from channel 123. timeout 1s.
    if (kbz_event_get(123, &buf, &len, 1000) == 0) {
     // if not timeout
     // buffer is available until next kbz_event_get call.
     printf("got: %s\n", buf);
    }
  }
  
}

client.c

#include <kbz-event.h>

void main() {
  // post event to channel 123.
  kbz_event_post(123, "hello", 6);
}

Usage2:

server.c

#include <kbz-event.h>

void main() {
  
  for (;;) {
    char *buf;
    int len;
    
    // get event from channel 123. wait forever(timeout=0).
    if (kbz_event_get(123, &buf, &len, 0) == 0) {
     char ans[128];
     sprintf(ans, "time now is %d", time(NULL));
     kbz_ack_event(123, buf, ans, strlen(ans)+1);
    }
  }
  
}

client.c

#include <kbz-event.h>

void main() {
  char *ans;
  int ans_len;
  
  // post an empty event to channel 123 and wait for answer.
  if (kbz_event_push(123, "", 0, &ans, &ans_len, 0) == 0) {
    printf("server says: %s\n", ans);
  }
}
