When to call pthread_exit?

Hey there.
I started working with PThreads recently and I have this one question. In my routine function, which is written in C++, should I call pthread_exit? I'm not sure about this since I heard someone mention that it isn't necessary in C++ code.

For example:

Code:

void* SomeFunction(void *data) {
   // do some stuff here
   // ...
   
   // do I need to call this?
   pthread_exit(NULL);
}

Any ideas? Thanks in advance.

You don't need to call this. But you need to call a pthread_join(Thread_ID,status) in the main program, from where you created the thread with pthread_create. This is called synchronization and is neccesary for the program to execute as planned.

Alrighty then, I'll look into pthread_join more closely.

Thanks!
