Draft: Inter-threads Communication

Pthread for inter-threads communication.

• Pthreads

There are a few ways to communicate between threads in pthread.

1. One way is to use shared memory.

Shared memory is a region of memory that is accessible to all threads in a process. To use shared memory, you first need to allocate a region of memory. You can do this using the malloc() function. Once you have allocated a region of memory, you can then share it with other threads by using the shmget() function.

2. Another way to communicate between threads in pthread is to use semaphores.

Semaphores are a type of synchronization primitive that allows you to control access to a shared resource. To use semaphores, you first need to create a semaphore. You can do this using the sem_init() function. Once you have created a semaphore, you can then use it to control access to a shared resource. For example, you can use a semaphore to ensure that only one thread can access a shared variable at a time.

3. Finally, you can also use pipes to communicate between threads in pthread.

Pipes are a type of inter-process communication (IPC) mechanism that allows you to send data between processes. To use pipes, you first need to create a pipe. You can do this using the pipe() function. Once you have created a pipe, you can then use it to send data between threads. For example, you can use a pipe to send a message from one thread to another.
