Data Structures
struct	pbl_mutex
	Recursive mutex. More...

Macros
#define	PBL_MUTEX_INITIALIZER   {.owner = NULL, .count = 0, .lock_lr = 0}
	Static initializer for an unlocked mutex.
#define	PBL_MUTEX_DEFINE(name)   struct pbl_mutex name = PBL_MUTEX_INITIALIZER
	Define an unlocked mutex, usable without pbl_mutex_init().

Functions

	Initialize a mutex in dynamically allocated memory.
void	pbl_mutex_deinit (struct pbl_mutex *m)
	Release a mutex before its memory is reused.
int	pbl_mutex_lock_lr (struct pbl_mutex *m, pbl_timeout_t timeout, uintptr_t lr)
	Lock a mutex, recording a given lock site.
static int	pbl_mutex_lock (struct pbl_mutex *m, pbl_timeout_t timeout)
	Lock a mutex.
void	pbl_mutex_unlock (struct pbl_mutex *m)
	Undo one lock of a mutex.
bool	pbl_mutex_is_owner (const struct pbl_mutex *m)
	Check whether the calling thread owns a mutex.
void	pbl_mutex_assert_held (const struct pbl_mutex *m, bool held)
	Assert that ownership of a mutex by the calling thread matches held.
