Is there any difference between returning double/float typed values and other types of value? For some reason, whenever I tried to return a double value, the value inside the address memory at the pointer is zero.

I suspect this behavior occurs because there's some slightly difference between returning a double pointer to values and an integer pointer to values...

Hi thanks for the tutorial, i have a quick question.
im using Lunix Ubnutu for this and when i'm not returning anything from the routine function, i get this error msg: warning: no return statement in function returning non-void
i know that it says you need to return something because, we declared the routine as
void *routine(void* args)
what i do for now is that i return something like | return (void*) 2;
just a random value, since im using the routine to print text only.
is there any thing i can do to fix this.
thank you

What is the benefit that you get, having pthread_exit(0) in main function (assume there is no join inside main)?? ..Are we freeing some process memory/ resources (if so, what are they) ?? consider the above example

One question, even If i dont return and try accessing that memory location, i should get the value in main thread. I mean if you can free from main thread, why not access the value.

Cant we use semaphores do the same task?

I don't think it is a memory leak. When the process finishes, the OS will deallocate all memory.
