Data Structures
struct	ISR_lock_Context
	Local ISR lock context for acquire and release pairs. More...

Macros
#define	ISR_LOCK_NEEDS_OBJECT   0
	If this define has a non-zero value, then the interrupt lock operations require an object of type ::ISR_lock_Control, otherwise no lock object is required.
#define	_ISR_lock_Initialize(_lock, _name)    do { (void) _name; } while (0)
	Initializes an ISR lock.
#define	_ISR_lock_Destroy(_lock)
	Destroys an ISR lock.
#define	_ISR_lock_Set_name(_lock, _name)
	Sets the name of an ISR lock.
#define	_ISR_lock_ISR_disable_and_acquire(_lock, _context)    _ISR_Local_disable( ( _context )->isr_level )
	Acquires an ISR lock.
#define	_ISR_lock_Release_and_ISR_enable(_lock, _context)    _ISR_Local_enable( ( _context )->isr_level )
	Releases an ISR lock.
#define	_ISR_lock_Acquire(_lock, _context)    do { (void) _context; } while ( 0 )
	Acquires an ISR lock inside an ISR disabled section.
#define	_ISR_lock_Release(_lock, _context)    do { (void) _context; } while ( 0 )
	Releases an ISR lock inside an ISR disabled section.
#define	_ISR_lock_Acquire_inline(_lock, _context)    do { (void) _context; } while ( 0 )
	Acquires an ISR lock inside an ISR disabled section (inline).
#define	_ISR_lock_Release_inline(_lock, _context)    do { (void) _context; } while ( 0 )
	Releases an ISR lock inside an ISR disabled section (inline).
#define	_ISR_lock_ISR_disable_profile(_context)
#define	_ISR_lock_ISR_disable(_context)
	Disables interrupts and saves the previous interrupt state in the ISR lock context.
#define	_ISR_lock_ISR_enable(_context)    _ISR_Local_enable( ( _context )->isr_level )
	Restores the saved interrupt state of the ISR lock context.
