C++ (Cpp) thread__set_comm Examples

Example #1

File: machine.c Project: arunmdavid/linux

int machine__init(struct machine *machine, const char *root_dir, pid_t pid)
{
	map_groups__init(&machine->kmaps);
	RB_CLEAR_NODE(&machine->rb_node);
	INIT_LIST_HEAD(&machine->user_dsos);
	INIT_LIST_HEAD(&machine->kernel_dsos);

	machine->threads = RB_ROOT;
	INIT_LIST_HEAD(&machine->dead_threads);
	machine->last_match = NULL;

	machine->kmaps.machine = machine;
	machine->pid = pid;

	machine->symbol_filter = NULL;
	machine->id_hdr_size = 0;

	machine->root_dir = strdup(root_dir);
	if (machine->root_dir == NULL)
		return -ENOMEM;

	if (pid != HOST_KERNEL_ID) {
		struct thread *thread = machine__findnew_thread(machine, 0,
								pid);
		char comm[64];

		if (thread == NULL)
			return -ENOMEM;

		snprintf(comm, sizeof(comm), "[guest/%d]", pid);
		thread__set_comm(thread, comm, 0);
	}

	return 0;
}

Example #2

static int thread__set_comm_adjust(struct thread *self, const char *comm)
{
    int ret = thread__set_comm(self, comm);

    if (ret)
        return ret;

    thread__comm_adjust(self);

    return 0;
}

Example #3

File: event.c Project: Aircell/asp-kernel

int event__process_comm(event_t *self)
{
	struct thread *thread = threads__findnew(self->comm.pid);

	dump_printf(": %s:%d\n", self->comm.comm, self->comm.pid);

	if (thread == NULL || thread__set_comm(thread, self->comm.comm)) {
		dump_printf("problem processing PERF_RECORD_COMM, skipping event.\n");
		return -1;
	}

	return 0;
}

Example #4

File: builtin-trace.c Project: 325116067/semc-qsd8x50

static int
process_comm_event(event_t *event, unsigned long offset, unsigned long head)
{
	struct thread *thread;

	thread = threads__findnew(event->comm.pid, &threads, &last_match);

	dump_printf("%p [%p]: PERF_RECORD_COMM: %s:%d\n",

	if (thread == NULL ||
	    thread__set_comm(thread, event->comm.comm)) {
