ACE_Local_Memory_Pool::ACE_Local_Memory_Pool | ( | const ACE_TCHAR * | backing_store_name = 0 , |
|
const OPTIONS * | options = 0 | |||
) |
Initialize the pool.
ACE_Local_Memory_Pool::~ACE_Local_Memory_Pool | ( | void | ) | [virtual] |
void * ACE_Local_Memory_Pool::init_acquire | ( | size_t | nbytes, | |
size_t & | rounded_bytes, | |||
int & | first_time | |||
) | [virtual] |
Ask system for initial chunk of local memory.
void * ACE_Local_Memory_Pool::acquire | ( | size_t | nbytes, | |
size_t & | rounded_bytes | |||
) | [virtual] |
Acquire at least nbytes from the memory pool. rounded_bytes is the actual number of bytes allocated.
int ACE_Local_Memory_Pool::release | ( | int | destroy = 1 |
) | [virtual] |
Instruct the memory pool to release all of its resources.
int ACE_Local_Memory_Pool::sync | ( | ssize_t | len = -1 , |
|
int | flags = MS_SYNC | |||
) | [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.
int ACE_Local_Memory_Pool::sync | ( | void * | addr, | |
size_t | len, | |||
int | flags = MS_SYNC | |||
) | [virtual] |
Sync len bytes of the memory region to the backing store starting at add_.
int ACE_Local_Memory_Pool::protect | ( | ssize_t | len = -1 , |
|
int | prot = PROT_RDWR | |||
) | [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.
int ACE_Local_Memory_Pool::protect | ( | void * | addr, | |
size_t | len, | |||
int | prot = PROT_RDWR | |||
) | [virtual] |
Change the protection of the pages of the mapped region to prot starting at addr up to len bytes.
int ACE_Local_Memory_Pool::seh_selector | ( | void * | ) | [virtual] |
Win32 Structural exception selector. The return value decides how to handle memory pool related structural exceptions. Returns 1, 0, or , -1.
int ACE_Local_Memory_Pool::remap | ( | void * | addr | ) | [virtual] |
Try to extend the virtual address space so that addr is now covered by the address mapping. Always returns 0 since we can't remap a local memory pool.
void * ACE_Local_Memory_Pool::base_addr | ( | void | ) | const [virtual] |
Return the base address of this memory pool, 0 if base_addr never changes.
ACE_BEGIN_VERSIONED_NAMESPACE_DECL void ACE_Local_Memory_Pool::dump | ( | void | ) | const [virtual] |
Dump the state of an object.
size_t ACE_Local_Memory_Pool::round_up | ( | size_t | nbytes | ) | [protected, virtual] |
Implement the algorithm for rounding up the request to an appropriate chunksize.
Declare the dynamic allocation hooks.
ACE_Unbounded_Set<char *> ACE_Local_Memory_Pool::allocated_chunks_ [protected] |
List of memory that we have allocated.
