Destructor.
MALLOC & ACE_Allocator_Adapter< MALLOC >::alloc | ( | void | ) |
Returns the underlying allocator.
|
virtual |
Associate name with pointer. If duplicates == 0 then do not allow duplicate name/pointer associations, else if duplicates != 0 then allow duplicate name/pointer associations. Returns 0 if successfully binds (1) a previously unbound name or (2) duplicates != 0, returns 1 if trying to bind a previously bound name and duplicates == 0, else returns -1 if a resource failure occurs.
Implements ACE_Allocator.
|
virtual |
Allocate nbytes, giving them all an initial_value.
Implements ACE_Allocator.
|
virtual |
Allocate n_elem each of size elem_size, giving them initial_value.
Implements ACE_Allocator.
|
virtual |
Dump the state of the object.
Implements ACE_Allocator.
|
virtual |
Locate name and pass out parameter via pointer. If found, return 0, returns -1 if name isn't found.
Implements ACE_Allocator.
|
virtual |
Returns 0 if the name is in the mapping and -1 if not.
Implements ACE_Allocator.
|
virtual |
Free ptr (must have been allocated by ACE_Allocator::malloc()).
Implements ACE_Allocator.
|
virtual |
Allocate nbytes, but don't give them any initial value.
Implements ACE_Allocator.
|
virtual |
Change the protection of the pages of the mapped region to prot starting at this->base_addr_
up to len bytes. If len == -1 then change protection of all pages in the mapped region.
Implements ACE_Allocator.
|
virtual |
Change the protection of the pages of the mapped region to prot starting at addr up to len bytes.
Implements ACE_Allocator.
|
virtual |
Remove any resources associated with this memory manager.
Implements ACE_Allocator.
|
virtual |
Sync len bytes of the memory region to the backing store starting at this->base_addr_
. If len == -1 then sync the whole region.
Implements ACE_Allocator.
|
virtual |
Sync len bytes of the memory region to the backing store starting at addr_
.
Implements ACE_Allocator.
|
virtual |
Associate name with pointer. Does not allow duplicate name/pointer associations. Returns 0 if successfully binds (1) a previously unbound name, 1 if trying to bind a previously bound name, or returns -1 if a resource failure occurs. When this call returns, pointer's value will always reference the void * that name is associated with. Thus, if the caller needs to use pointer (e.g., to free it) a copy must be maintained by the caller.
Implements ACE_Allocator.
|
virtual |
Unbind (remove) the name from the map. Don't return the pointer to the caller
Implements ACE_Allocator.
|
virtual |
Break any association of name. Returns the value of pointer in case the caller needs to deallocate memory.
Implements ACE_Allocator.
|
private |
ALLOCATOR instance, which is owned by the adapter.
