Constructor & Destructor Documentation

ACE_Local_Memory_Pool::ACE_Local_Memory_Pool const ACE_TCHAR backing_store_name = 0,
const OPTIONS options = 0
 

Initialize the pool.

Member Function Documentation

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.

void * ACE_Local_Memory_Pool::base_addr void   )  const [virtual]
 

Return the base address of this memory pool, 0 if base_addr never changes.

void ACE_Local_Memory_Pool::dump void   )  const [virtual]
 

Dump the state of an object.

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.

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::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::release int  destroy = 1  )  [virtual]
 

Instruct the memory pool to release all of its resources.

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.

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.

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::sync void *  addr,
size_t  len,
int  flags = MS_SYNC
[virtual]
 

Sync <len> bytes of the memory region to the backing store starting at <addr_>.

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.
