Hello all .
i am a newbie to the boost community . i recently started learning about
threads in boost . now there are some questions i would like to ask :
1.where can i find examples showing practical uses of boost::thread
features?
2.how can i get all threads ID issued by me in my app?
3.how can i iterate through running threads in my app ?
4.is there any kind of means to get all the running threads using boost
library? if it does whats the calss? if it doesnt how can i do that?
5.can i resume a thread after pausing it ? ( how can i pause a thread? )
6. how can i share a variable between two or more threads , suppose i have
a loop , i want two threads to simultaneously iterate through it , if
thread1 counted to 3, thread2 continues it from 4 and so on . ?
i already tried
