Member Function Documentation

ACE_INLINE int ACE_Shared_Memory_SV::close (  void    )  [virtual]

Close down the shared memory segment. Implements ACE_Shared_Memory.

void ACE_Shared_Memory_SV::dump (  void    )  const

Dump the state of an object.

ACE_INLINE int ACE_Shared_Memory_SV::free (  void *    p )  [virtual]

ACE_INLINE ACE_HANDLE ACE_Shared_Memory_SV::get_id (  void    )  const [virtual]

Return the ID of the shared memory segment (i.e., a System V shared memory internal id). Implements ACE_Shared_Memory.

ACE_INLINE int ACE_Shared_Memory_SV::get_segment_size (  void    )  const [virtual]

Return the size of the shared memory segment. Implements ACE_Shared_Memory.

ACE_INLINE void * ACE_Shared_Memory_SV::malloc (  size_t    = 0 )  [virtual]

Create a new chuck of memory containing <size> bytes. Implements ACE_Shared_Memory.

ACE_INLINE int ACE_Shared_Memory_SV::open (  key_t    id, int    length, int    create = ACE_Shared_Memory_SV::ACE_OPEN, int    perms = ACE_DEFAULT_FILE_PERMS, void *    addr = 0, int    flags = 0 )

ACE_INLINE int ACE_Shared_Memory_SV::remove (  void    )  [virtual]

Remove the underlying shared memory segment. Implements ACE_Shared_Memory.
