Data Structures
struct	critical_section

Typedefs
typedef struct __packed_aligned critical_section	critical_section_t

Functions
void	critical_section_init (critical_section_t *crit_sec)
	Initialise a critical_section structure allowing the system to assign a spin lock numberThe critical section is initialized ready for use, and will use a (possibly shared) spin lock number assigned by the system. Note that in general it is unlikely that you would be nesting critical sections, however if you do so you must use critical_section_init_with_lock_num to ensure that the spin lock's used are different.

void	critical_section_init_with_lock_num (critical_section_t *crit_sec, uint lock_num)
	Initialise a critical_section structure assigning a specific spin lock number. More...
static void	critical_section_enter_blocking (critical_section_t *crit_sec)
	Enter a critical_sectionIf the spin lock associated with this critical section is in use, then this method will block until it is released. More...
static void	critical_section_exit (critical_section_t *crit_sec)
	Release a critical_section. More...
void	critical_section_deinit (critical_section_t *crit_sec)
	De-Initialise a critical_section created by the critical_section_init methodThis method is only used to free the associated spin lock allocated via the critical_section_init method (it should not be used to de-initialize a spin lock created via critical_section_init_with_lock_num). After this call, the critical section is invalid. More...
static bool	critical_section_is_initialized (critical_section_t *crit_sec)
	Test whether a critical_section has been initialized. More...
