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
