This repository contains a kernel module that provides a new inter-process communication (IPC) mechanism called a message slot. A message slot is a character device file through which processes can communicate. Each message slot device can have multiple message channels active concurrently, allowing multiple processes to use it. The module supports setting a channel ID using ioctl(), and sending/receiving messages using write() and read() system calls.

1. Compile the kernel module:

   make

2. Load the kernel module:

   sudo insmod message_slot.ko

3. Create a message slot device file:

   sudo mknod /dev/slot0 c 235 0
   sudo chmod 666 /dev/slot0

1. Load the kernel module:

   sudo insmod message_slot.ko

2. Create a message slot file:

   sudo mknod /dev/slot0 c 235 0
   sudo chmod 666 /dev/slot0

3. Send a message:

   ./message_sender /dev/slot0 1 "Hello, World!"

4. Read the message:

   ./message_reader /dev/slot0 1
   Hello, World!
