Initialize ACE_Malloc. This constructor passes <pool_name> to initialize the memory pool, and uses to automatically extract out the name used for the underlying lock name (if necessary). |

Initialize ACE_Malloc. This constructor passes <pool_name> to initialize the memory pool, and uses <lock_name> to automatically extract out the name used for the underlying lock name (if necessary). In addition, <options> is passed through to initialize the underlying memory pool. |
|
This is necessary to work around template bugs with certain C++ compilers.
|
|
Destructor.
|
|
Returns a count of the number of available chunks that can hold <size> byte allocations. Function can be used to determine if you have reached a water mark. This implies a fixed amount of allocated memory.
|
|
Return cb_ptr value.
|
|
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. |
|
Allocate <n_elem> each of size <elem_size>, giving them <initial_value>.
|
|
Allocate <nbytes>, giving them <initial_value>.
|
|
Dump the state of an object.
|
|
Returns 0 if <name> is in the mapping. -1, otherwise.
|
|
Locate <name> and pass out parameter via <pointer>. If found, return 0, returns -1 if failure occurs.
|
|
Deallocate memory pointed to by <ptr>, which must have been allocated previously by <this->malloc>.
|
|
Allocate <nbytes>, but don't give them any initial value.
|
|
Returns a reference to the underlying memory pool.
|
|
Returns a pointer to the lock used to provide mutual exclusion to an allocator.
|
|
Initialize the Malloc pool.
|
|
Change the protection of the pages of the mapped region to <prot> starting at up to <len> bytes.
|
|
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. |
|
Get Reference counter.
|
|
Release ref counter.
|
|
Releases resources allocated by .
|
|
Associate <name> with <pointer>. Assumes that locks are held by callers.
|
|
Try to locate <name>. If found, return the associated , else returns 0 if can't find the <name>. Assumes that locks are held by callers. Remember to cast the return value to ACE_CB::ACE_Name_Node*. |
|
Deallocate memory. Assumes that locks are held by callers.
|
|
Allocate memory. Assumes that locks are held by callers.
|
|
Sync <len> bytes of the memory region to the backing store starting at .
|
|
Sync <len> bytes of the memory region to the backing store starting at <this->base_addr_>. If <len> == -1 then sync the whole region. |
|
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. |
|
Unbind (remove) one association of <name> to <pointer>. Returns the value of pointer in case the caller needs to deallocate memory. If you want to remove all occurrences of <name> you'll need to call this method multiple times until it fails... |
|
Unbind (remove) the name from the map. Don't return the pointer to the caller. If you want to remove all occurrences of <name> you'll need to call this method multiple times until it fails... |
