title: Is there exist a system call in Ubuntu Linux which could make subthread directly read main thread's cmd parameter?
body: <p>Recently i'm doing my parallel programming exercise, which made me curious to the question of parameter sending. As we all know we could use function pthread_create to create a subthread which could execute function where pthread_create's parameter mentioned, as the parameter sending does, but if i want to sending more parameter, i have to define a global structual body. Its quite complex as i wonder, if there have a system call could quickly passing those parameter directly to the subthread?</p>
