hi,
	i have written a program which contains  3 thread as  shown.

cyg_user_start(void)
{

printf("entering two threads cyg_user_start() function\n");

cyg_mutex_init(&cliblock);
	cyg_thread_create(3,simple_program,(cyg_addrword_t)2,
	"simple_program_Thread ",(void*) stack[2],4096,
	 &simple_program_Thread,&thread_s[2]);
	cyg_thread_create(4,simple_program1,(cyg_addrword_t)3,
	"simple_program1_Thread",(void*) stack[3],4096,
	 &simple_program1_Thread,&thread_s[3]);
	 cyg_thread_create(5,simple_program2,(cyg_addrword_t)4,
	"simple_program2_Thread",(void*) stack[4],4096,
	 &simple_program2_Thread,&thread_s[4]);

cyg_thread_resume(simple_program_Thread);
cyg_thread_resume(simple_program1_Thread);
cyg_thread_resume(simple_program2_Thread);
}
cyg_alarm_t alarm_Tbcn_func;

void simple_program(cyg_addrword_t data )
{
	int message=(int) data;
	unsigned int i;
	printf("i am thread %d before delay\n",message);

	curr_time=cyg_real_time_clock();
	cyg_clock_to_counter(curr_time,&handle_counterTbcn);
        cyg_alarm_create(handle_counterTbcn, alarm_Tbcn_func,5500,
                	&handle_alarmTbcn, &alarm_Tbcn);
	cyg_alarm_initialize(handle_alarmTbcn,cyg_current_time()+200,0);

		cyg_thread_delay(3);
		while(1)
		{
			if(var==1)
			{
				printf(" hello");
				break;
			}
		}
}

void  simple_program1(cyg_addrword_t data )
{
	int message=(int) data;
	printf("i am thread %d\n",message);
}

void  simple_program2(cyg_addrword_t data )
{
	int message=(int) data;
	printf("i am thread %d\n",message);
	while(1)
	{
	}
}
 void alarm_Tbcn_func( cyg_handle_t alarmTbcn,cyg_addrword_t data)
{
	var=1;
	printf(" i am  in alarm function\n");
}


there is cyg_thread _delay(3) in t1.the control goes to t2 and then
t3.In t3 i have infinite while loop.The control is not going to t1.Is
there any way so that i can signal to t1 that thread delay is over and
it can continue its flow.If so then how it is? 
	
thank u in advance
