Hi All!
I need your help.I want to know how to check whether thread is alive or
not.I go through pthread_kill function
pthread_kill(thread_id,0);
i have read If sig(2nd argument) is 0, a validity check is performed for
the existence of the target
thread (thread_id(1st Argument)).
Upon successful completion, the function returns a value of
0. Otherwise the function returns an error number. If the
pthread_kill() function fails, no signal is sent.
I want to know few things:
i)pthread_kill will be successfully executed(in that case it will return
0)but how do we check whether thread_id exists or not.
ii)i want to know how the successful execution of pthread_kill function
determines whether thread_id exists or not.
iii) or if possible i want to know how it is related to successful execution
of function pthread_kill.
in very simple terms, i want to know if thread_id doesnot exist,i will get
value other than 0 and if exists i will get the value 0.That this what i
have mentioned just now means in above synopsis of pthread_kill function.
Dear all ! I need your help inresolving the fundas behind it.please help me
and give me precise justification that will let concepts clear about
pthread_function.
thanksandregards
