What would happen if a thread try to delete an object which is locked by another thread (using pthread_mutex_lock) ???

On a MS windows platform , mutex cannot lock any object...
When a mutex has been hold by someone thread(e.g. Thread A), any threads that attemping to hold this mutex will be hung until the mutex was released by Thread A.

I am not sure how you can delete a mutex lock. probably you meant to say that you will use pthread_mutex_destroy on locked mutex.
It is safe to destroy an initialized mutex that is unlocked.
Attempting to destroy a locked mutex results in undefined behavior.

Why do you want to destroy the mutex while the thread is still running?
