What are pthreads in C++?

Pthreads, or POSIX threads, are a standard for multi-threading in C and C++. They allow concurrent execution of code.

How do I create a thread using pthreads?

You can create a thread using the pthread_create function, which takes a thread identifier, attributes, the function to execute, and its arguments.

Can you show me a simple example?

Sure! Here's a basic example:

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

void* myThreadFun(void* arg) {
    std::cout << "Hello from thread!" << std::endl;
    return nullptr;
}

int main() {
    pthread_t thread;
    pthread_create(&thread, nullptr, myThreadFun, nullptr);
    pthread_join(thread, nullptr);
    return 0;
}

What are some common issues when using pthreads?

Common issues include race conditions, deadlocks, and resource contention. Proper synchronization is key to avoid these.
