Message Receive Example (QNX Neutrino) — Qnx-neutrino-rtos Code
Receive a message from another process using QNX message passing.
#include <stdio.h>
#include <sys/neutrino.h>
#include <unistd.h>
int main() {
int chid = ChannelCreate(0);
char buf[128];
MsgReceive(chid, buf, sizeof(buf), NULL);
printf("Received: %s\n", buf);
ChannelDestroy(chid);
return 0;
