Question on creation of Thread pool

dear sir/madam
presently i am in a process of creating a multithread pool using

clone() system call in unix with c programming.
i am facing some problem ie., i am able create multithread pool and

able to keep all the threads in wait state,but when i call kill

(afunction revoke a thread after stopping it through raise

function) all the threads in the pool are revoking instead of only

one.In order to make only single thread to invoke and keep the

rest in wait condition i need to set a flag in clone system call

but i am unable to find that flag.I tried it with all flags that i

got in man and internet but i could not get it.so can anyone send

me the code for the same?

Thanks
Radha

Thread::Pool::Simple - A simple thread-pool implementation SYNOPSIS
use Thread::Pool::Simple; my $pool = Thread::Pool::Simple->new( min => 3, # at least 3 workers max => 5, # at most 5 workers load => 10, # increase worker if on average every worker has 10 jobs waiting init => [&init_handle, $arg1, $arg2, ...] # run before creating worker thread pre => [&pre_handle, $arg1, $arg2, ...] # run after creating worker thread do => [&do_handle, $arg1, $arg2, ...] # job handler for each worker post => [&post_handle, $arg1, $arg2, ...] # run before worker threads end passid => 1, # whether to pass the job id as the first argument to the &do_handle lifespan => 10000, # total jobs handled by each worker ); my ($id1) = $pool->add(@arg1); # call in list context my $id2 = $pool->add(@arg2); # call in scalar conetxt $pool->add(@arg3) # call in void context my @ret = $pool->remove($id1); # get result (block) my $ret = $pool->remove_nb($id2); # get result (no block) $pool->cancel($id1); # cancel the job $pool->cancel_all(); # cancel all jobs $pool->join(); # wait till all jobs are done $pool->detach(); # don't wait.
