sizeof | Get size of a JavaScript object | Script Programming library

calloc is allocating the amount of memory you asked for on the heap. The pointer is allocated by your compiler either in registers or on the stack. In this case, calloc is actually allocating enough memory for 4 ints on the heap (which on most systems is going to be 16 bytes, but for the arduino uno it would be 8 because the sizeof(int) is 2), then storing the pointer to that allocated memory in your register/stack location.

For the bonus question: Arduino uses C++ instead of C, and that means that it uses C++'s stronger type system. void * and int * are different types, so it's complaining. You should cast the return value of malloc when using C++.

select() can set a timeout for the connection part.

Yes, but only if you put the socket into non-blocking mode before calling connect(), so that connect() exits immediately and then the code can use select() to wait for the socket to report when the connect operation has finished. But the code shown is not doing that.

setsockopt() with timeval can timeout the receiving portion of the code

Yes, though select() can also be used to timeout a read operation, as well. Simply call select() first, and then call recv() only if select() reports that the socket is readable (has pending data to read).

Try something like this:

Don't know about metal specifically, but in ordinary C, you'd want to put f and byteArray inside a union

Here's some sample code:

You're supposed to free memory right after the last time it will be used. In your program, after the while loop in recursion, Energy isn't used again, so you should free it right after that (i.e., right before return event_counter;).

The functions Hash_Inline and Hash_FunctionCall are not equivalent:

• The first statement in Hash_Inline rotates by 1, but in Hash_FunctionCall it rotates by curIndex.
• For RotateLeft you may have probably meant:

I'm trying to parallelize a merge-sort algorithm. What I'm doing is dividing the input array for each thread, then merging the threads results.

Ok, but yours is an unnecessarily difficult approach. At each step of the merge process, you want half of your threads to wait for the other half to finish, and the most natural way for one thread to wait for another to finish is to use pthread_join(). If you wanted all of your threads to continue with more work after synchronizing then that would be different, but in this case, those that are not responsible for any more merges have nothing at all left to do.

This is what I've tried:

You have to assign the number of elements of the array to return (2 in this case) to what the argument returnSize points at (*returnSize) to tell the judge system how large the array you returned is.

Because once all command are executed, the terminal close itself.

I had the same problem, man. I want to transplant tflite to the development board of CEVA. There is no problem in compiling. In the process of running, there is also an error in AddBuiltin(full_connect). At present, the only possible situation I guess is that some devices can not support tflite.
