👍, nice catch. It does beg the question though, shouldn't we just shorten it to:
if (pthread_mutex_init(&mutex_buf[i], NULL))
return 0;..to increase readability?

For consistency it would then be nice to eliminate all the ret variables in the file as none of them is used besides for checking call result. Should I update the pull request?

Variable ret is only used in case of USE_THREADS_POSIX. Other cases will issue a warning about unused variable.
