To fully release the lock, a thread must invoke `unlock` the same number of times it invoked `lock` and `tryLock`. The behavior is undefined unless the calling thread currently owns the lock on this recursive mutex. == Synopsis Declared in `<bslmt_recursivemutex.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- void unlock(); ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
