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
