Linux implements all threads as standard processes. The Linux kernel does not provide any special scheduling semantics or data structures to represent threads. Instead, a thread is merely a process that shares certain resources with other processes.

How threads are created in Linux?

It uses the pthread_create() function to create two threads. The starting function for both the threads is kept same. Inside the function ‘doSomeThing()’, the thread uses pthread_self() and pthread_equal() functions to identify whether the executing thread is the first one or the second one as created.

Does Linux scheduler threads or processes?

3 Answers. The Linux kernel scheduler is actually scheduling tasks, and these are either threads or (single-threaded) processes. A process is a non-empty finite set (sometimes a singleton) of threads sharing the same virtual address space (and other things like file descriptors, working directory, etc etc…).
