What are some examples of threading in C programming?

In C programming, threading can be implemented using the pthread library. For example, you can create a simple thread that prints numbers.

Can you show me a code snippet for that?

Sure! Here's a basic example:

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

void* print_numbers(void* arg) {
    for (int i = 1; i <= 5; i++) {
        printf("%d\n", i);
    }
    return NULL;
}

int main() {
    pthread_t thread;
    pthread_create(&thread, NULL, print_numbers, NULL);
    pthread_join(thread, NULL);
    return 0;
}

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 arguments for that function.

Are there any potential issues with threading I should be aware of?

Yes, common issues include race conditions, deadlocks, and resource contention. Proper synchronization mechanisms like mutexes can help.
