Macros
#define	CORE_MUTEX_STATUS_LAST   CORE_MUTEX_STATUS_CEILING_VIOLATED
	The last status value. More...
#define	_CORE_mutex_Seize_interrupt_trylock(_mutex, _executing, _lock_context)   _CORE_mutex_Seize_interrupt_trylock_body( _mutex, _executing, _lock_context )
	The default is to favor speed and inlining this definitely saves a few instructions. More...
#define	_CORE_mutex_Check_dispatch_for_seize(_wait)
	Verifies that a mutex blocking seize is performed safely. More...
#define	_CORE_mutex_Seize(_the_mutex, _executing, _id, _wait, _timeout, _lock_context)
	This method is used to obtain a core mutex. More...

Typedefs
typedef void(*	CORE_mutex_API_mp_support_callout) (Thread_Control *, Objects_Id)
	Callout which provides to support global/multiprocessor operations. More...

Enumerations
enum	CORE_mutex_Status {   CORE_MUTEX_STATUS_SUCCESSFUL, CORE_MUTEX_STATUS_UNSATISFIED_NOWAIT, CORE_MUTEX_STATUS_NOT_OWNER_OF_RESOURCE, CORE_MUTEX_WAS_DELETED,   CORE_MUTEX_TIMEOUT, CORE_MUTEX_STATUS_CEILING_VIOLATED }
	The possible Mutex handler return statuses. More...

Functions
CORE_mutex_Status	_CORE_mutex_Initialize (CORE_mutex_Control *the_mutex, Thread_Control *executing, const CORE_mutex_Attributes *the_mutex_attributes, bool initially_locked)
	Initializes the mutex based on the parameters passed. More...

void	_CORE_mutex_Seize_interrupt_blocking (CORE_mutex_Control *the_mutex, Thread_Control *executing, Watchdog_Interval timeout, ISR_lock_Context *lock_context)
	Performs the blocking portion of a mutex obtain. More...
RTEMS_INLINE_ROUTINE void	_CORE_mutex_Seize_body (CORE_mutex_Control *the_mutex, Thread_Control *executing, Objects_Id id, bool wait, Watchdog_Interval timeout, ISR_lock_Context *lock_context)

CORE_mutex_Status	_CORE_mutex_Surrender (CORE_mutex_Control *the_mutex, Objects_Id id, CORE_mutex_API_mp_support_callout api_mutex_mp_support, ISR_lock_Context *lock_context)
	Frees a unit to the mutex. More...
void	_CORE_mutex_Flush (CORE_mutex_Control *the_mutex, Thread_queue_Flush_callout remote_extract_callout, uint32_t status)
	Flush all waiting threads. More...
RTEMS_INLINE_ROUTINE bool	_CORE_mutex_Is_locked (const CORE_mutex_Control *the_mutex)
	Is mutex locked. More...
RTEMS_INLINE_ROUTINE bool	_CORE_mutex_Is_fifo (const CORE_mutex_Attributes *the_attribute)
	Does core mutex use FIFO blocking. More...
RTEMS_INLINE_ROUTINE bool	_CORE_mutex_Is_priority (CORE_mutex_Attributes *the_attribute)
	Doex core mutex use priority blocking. More...
RTEMS_INLINE_ROUTINE bool	_CORE_mutex_Is_inherit_priority (CORE_mutex_Attributes *the_attribute)
	Does mutex use priority inheritance. More...
RTEMS_INLINE_ROUTINE bool	_CORE_mutex_Is_priority_ceiling (CORE_mutex_Attributes *the_attribute)
	Does mutex use priority ceiling. More...
