C++ (Cpp) sys_nop Beispiele

Beispiel #1

Datei: kmain-fork.c Projekt: Gazolik/OS-RaspberryPi

int process()
{
	int32_t cpt = 10;
	
	int pid = sys_fork();
	if (pid == -1)
	{
		// failed, should not happen
	}
	else if (pid == 0)
	{
		// Child
		cpt--;
		sys_nop();
	}
	else
	{
		// Parent
		cpt++;
		sys_nop();
	}
	
	return 0;
}

Beispiel #2

Datei: vm.c Projekt: XilongPei/libsel4arm-vmm
