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.
