virtual void* ACE_Allocator::calloc | ( | size_type | nbytes, | |
char | initial_value = '\0' | |||
) | [pure virtual] |
Allocate nbytes, giving them initial_value.
Implemented in ACE_New_Allocator, ACE_Static_Allocator_Base, ACE_Cached_Allocator< T, ACE_LOCK >, ACE_Dynamic_Cached_Allocator< ACE_LOCK >, and ACE_Allocator_Adapter< MALLOC >.
virtual void* ACE_Allocator::calloc | ( | size_type | n_elem, | |
size_type | elem_size, | |||
char | initial_value = '\0' | |||
) | [pure virtual] |
Allocate <n_elem> each of size elem_size, giving them initial_value.
Implemented in ACE_New_Allocator, ACE_Static_Allocator_Base, ACE_Cached_Allocator< T, ACE_LOCK >, ACE_Dynamic_Cached_Allocator< ACE_LOCK >, and ACE_Allocator_Adapter< MALLOC >.
virtual void ACE_Allocator::free | ( | void * | ptr | ) | [pure virtual] |
Free <ptr> (must have been allocated by <ACE_Allocator::malloc>).
Implemented in ACE_New_Allocator, ACE_Static_Allocator_Base, ACE_Cached_Allocator< T, ACE_LOCK >, ACE_Dynamic_Cached_Allocator< ACE_LOCK >, and ACE_Allocator_Adapter< MALLOC >.
virtual int ACE_Allocator::remove | ( | void | ) | [pure virtual] |
Remove any resources associated with this memory manager.
Implemented in ACE_New_Allocator, ACE_Static_Allocator_Base, and ACE_Allocator_Adapter< MALLOC >.
virtual int ACE_Allocator::bind | ( | const char * | name, | |
void * | pointer, | |||
int | duplicates = 0 | |||
) | [pure 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 assocations. 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.
Implemented in ACE_New_Allocator, ACE_Static_Allocator_Base, and ACE_Allocator_Adapter< MALLOC >.
virtual int ACE_Allocator::trybind | ( | const char * | name, | |
void *& | pointer | |||
) | [pure 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.
Implemented in ACE_New_Allocator, ACE_Static_Allocator_Base, and ACE_Allocator_Adapter< MALLOC >.
virtual int ACE_Allocator::find | ( | const char * | name, | |
void *& | pointer | |||

Implemented in ACE_New_Allocator, ACE_Static_Allocator_Base, and ACE_Allocator_Adapter< MALLOC >.
virtual int ACE_Allocator::find | ( | const char * | name | ) | [pure virtual] |
Returns 0 if the name is in the mapping. -1, otherwise.
Implemented in ACE_New_Allocator, ACE_Static_Allocator_Base, and ACE_Allocator_Adapter< MALLOC >.
virtual int ACE_Allocator::unbind | ( | const char * | name | ) | [pure virtual] |
Unbind (remove) the name from the map. Don't return the pointer to the caller
Implemented in ACE_New_Allocator, ACE_Static_Allocator_Base, and ACE_Allocator_Adapter< MALLOC >.
virtual int ACE_Allocator::unbind | ( | const char * | name, | |
void *& | pointer | |||
) | [pure virtual] |
Break any association of name. Returns the value of pointer in case the caller needs to deallocate memory.

Sync len bytes of the memory region to the backing store starting at this->base_addr_
. If len == -1 then sync the whole region.
Implemented in ACE_New_Allocator, ACE_Static_Allocator_Base, and ACE_Allocator_Adapter< MALLOC >.

Sync len bytes of the memory region to the backing store starting at addr.

virtual int ACE_Allocator::protect | ( | ssize_t | len = -1 , |
|
int | prot = PROT_RDWR | |||
) | [pure 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.
Implemented in ACE_New_Allocator, ACE_Static_Allocator_Base, and ACE_Allocator_Adapter< MALLOC >.
