I have some questions about pthreads in linux: Is it the case that pthread_t is it a datatype similar to int and char indicating we are defining a thread? If so, how much size does it take? 2 bytes or 4 bytes? Does the compiler allocate memory to pthread_t thread1 immediately after that statement or does it wait until it a pthread_create() call? How does one set the thread attributes, and what is their typical use? Can one only pass more than one argument in the pthread_create() call? If so, how? I have lots of things on my mind like this. Please also feel free to suggest any good sites or documents to read.
