Data Structures
struct	rtems_interrupt_server_action

Macros
#define	RTEMS_INTERRUPT_UNIQUE   ((rtems_option) 0x00000001)
	Makes the interrupt handler unique. Prevents other handler from using the same interrupt vector.
#define	RTEMS_INTERRUPT_SHARED   ((rtems_option) 0x00000000)
	Allows that this interrupt handler may share a common interrupt vector with other handler.
#define	RTEMS_INTERRUPT_REPLACE   ((rtems_option) 0x00000002)
	Forces that this interrupt handler replaces the first handler with the same argument.
#define	RTEMS_INTERRUPT_IS_UNIQUE(options)   ((options) & RTEMS_INTERRUPT_UNIQUE)
	Returns true if the interrupt handler unique option is set.
#define	RTEMS_INTERRUPT_IS_SHARED(options)   (!RTEMS_INTERRUPT_IS_UNIQUE( options))
	Returns true if the interrupt handler shared option is set.
#define	RTEMS_INTERRUPT_IS_REPLACE(options)   ((options) & RTEMS_INTERRUPT_REPLACE)
	Returns true if the interrupt handler replace option is set.
#define	RTEMS_INTERRUPT_SERVER_DEFAULT   0
	The interrupt server index of the default interrupt server.

Typedefs
typedef void(*	rtems_interrupt_handler) (void *)
	Interrupt handler routine type.
typedef void(*	rtems_interrupt_per_handler_routine) (void *, const char *, rtems_option, rtems_interrupt_handler, void *)
	Interrupt handler iteration routine type. More...
typedef struct rtems_interrupt_server_action	rtems_interrupt_server_action
