Detailed Description

Macro Definition Documentation

◆ SEMAPHORE_INFORMATION_DEFINE

#define SEMAPHORE_INFORMATION_DEFINE	(	max,
		scheduler_count
	)

Value:

  OBJECTS_INFORMATION_DEFINE( \
    _Semaphore, \
    OBJECTS_CLASSIC_API, \
    OBJECTS_RTEMS_SEMAPHORES, \
    Semaphore_Control, \
    max, \
    OBJECTS_NO_STRING_NAME, \
    _Semaphore_MP_Send_extract_proxy \
  )

Macro to define the objects information for the Classic Semaphore objects.

This macro should only be used by <rtems/confdefs.h>.

Parameters

max	The configured object maximum (the OBJECTS_UNLIMITED_OBJECTS flag may be set).
scheduler_count	The configured scheduler count (only used in SMP configurations).

Enumeration Type Documentation

◆ Semaphore_Variant

enum Semaphore_Variant

Classic semaphore variants.

Must be in synchronization with Semaphore_Control::variant.

Function Documentation

◆ _Semaphore_Allocate()

RTEMS_INLINE_ROUTINE Semaphore_Control * _Semaphore_Allocate ( void )

Allocates a semaphore control block from the inactive chain of free semaphore control blocks.

This function allocates a semaphore control block from the inactive chain of free semaphore control blocks.

◆ _Semaphore_Free()

RTEMS_INLINE_ROUTINE void _Semaphore_Free ( Semaphore_Control * the_semaphore )

Frees a semaphore control block to the inactive chain of free semaphore control blocks.

This routine frees a semaphore control block to the inactive chain of free semaphore control blocks.
