How do I use the pthreads library in C?

The pthreads library allows you to create and manage threads in C. Would you like a simple example?

Yes, please provide a basic example.

Here's a simple example:

#include <pthread.h>
#include <stdio.h>

void* printMessage(void* message) {
    printf("%s\n", (char*)message);
    return NULL;
}

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

This code creates a thread that prints a message.

What does pthread_create do in this example?

pthread_create is used to create a new thread. It takes the thread identifier, attributes, the function to execute, and the argument to pass to that function.

How do I compile a program that uses pthreads?

To compile a program using pthreads, you need to link the pthread library. Use the command: gcc -o myprogram myprogram.c -lpthread.
