How do I use pthreads in C++?

To use pthreads in C++, you need to include the pthread.h header and link against the pthread library. What specific aspect are you interested in?

Can you show me a simple example?

Sure! Here's a basic example:

#include <iostream>
#include <pthread.h>

void* printMessage(void* message) {
    std::cout << (char*)message << std::endl;
    return nullptr;
}

int main() {
    pthread_t thread;
    const char* message = "Hello from the thread!";
    pthread_create(&thread, nullptr, printMessage, (void*)message);
    pthread_join(thread, nullptr);
    return 0;
}

This creates a thread that prints a message.

What do pthread_create and pthread_join do?

pthread_create starts a new thread, while pthread_join waits for the specified thread to finish before continuing.

Are there any common pitfalls when using pthreads?

Yes, common pitfalls include forgetting to join threads, race conditions, and improper handling of shared resources.
