What are some examples of thread-safe functions in C?

What are some examples of thread-safe functions in C?

Thread-safe functions in C are designed to be safely called by multiple threads simultaneously. Examples include malloc, free, and functions from the POSIX threads library like pthread_create.

Can you explain why malloc is considered thread-safe?

malloc is thread-safe because it manages memory allocation in a way that prevents data corruption when multiple threads request memory at the same time.

Are there any specific libraries that provide thread-safe functions?

Yes, libraries like the C11 standard library and POSIX threads provide several thread-safe functions, such as pthread_mutex_lock and pthread_cond_wait.

What should I be cautious about when using thread-safe functions?

Even with thread-safe functions, you should be cautious about race conditions and ensure proper synchronization when accessing shared resources.
