Unexpected (Mariothedog) Mac OS

Question or issue on macOS:

Unexpected (mariothedog) Mac Os Download
Unexpected (mariothedog) Mac Os Update
Unexpected (mariothedog) Mac Os X
Unexpected (mariothedog) Mac Os Catalina

Errors can lead to unexpected behavior when using your Mac, and significant errors might even prevent your Mac from starting up completely. Before proceeding, make sure that you have a current backup of your Mac, in case you need to recover damaged files or Disk Utility finds errors that it can't repair.
Question or issue on macOS: I wrote a simple program solving the Readers-Writers problem using semaphores. It runs perfectly on Linux os, but when I run it on my Mac osX I get unexpected results and I can’t figure out why. My Program: #include #include #include #include #include void. function1(void. val); void. function2(void. val); //.

I wrote a simple program solving the Readers-Writers problem using semaphores. It runs perfectly on Linux os, but when I run it on my Mac osX I get unexpected results and I can’t figure out why.

I am running OS Mojave 10.14.5, which actually has an update. Could this be the issue? I do not believe I have a.lock file next to the catalog on my system. If you mean physically next to my catalog on my HD, I only have a.lrdata file near it.

My Program:

The output I receive on Linux (what it’s supposed to look like):

The output on Mac osX (unexpected):

How to solve this problem?

Solution no. 1:

Check the error return on the sem_init calls; I bet you’ll find the OS X version returning a “Function not implemented” error.

This is because unnamed POSIX semaphores are not implemented on OS X. You need to use named semaphores, or pthread mutex/condition variables.

Solution no. 2:

Just for completeness, here’s a working Mac OS X version using sem_open() and sem_unlink() instead of sem_init() and sem_destroy().

Hope this helps!
