How do I handle errors in pthreads?

In pthreads, you can handle errors by checking the return values of pthread functions. For example, if you call pthread_create, it returns 0 on success and an error code on failure.

What are some common error codes I should be aware of?

Common error codes include EAGAIN, which indicates insufficient resources, and EINVAL, which indicates invalid settings.

Can you give me an example of error handling in a pthreads program?

Sure! Here's a simple example:

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

void* threadFunction(void* arg) {
    // Thread work here
    return NULL;
}

int main() {
    pthread_t thread;
    int result = pthread_create(&thread, NULL, threadFunction, NULL);
    if (result != 0) {
        fprintf(stderr, "Error creating thread: %d\n", result);
        return 1;
    }
    pthread_join(thread, NULL);
    return 0;
}

What happens if I don't handle errors in pthreads?

If you don't handle errors, your program may behave unpredictably, crash, or lead to resource leaks, making debugging difficult.
