Symbolic constants
#define APR_MEMNODE_T_SIZE APR_ALIGN_DEFAULT(sizeof(apr_memnode_t)) |
The base size of a memory node - aligned.
typedef struct apr_allocator_t apr_allocator_t |
the allocator structure
typedef struct apr_memnode_t apr_memnode_t |
the structure which holds information about the allocation
APR_DECLARE | ( | apr_memnode_t * | ) |
Allocate a block of mem from the allocator
allocator | The allocator to allocate from |
size | The size of the mem to allocate (excluding the memnode structure) |
APR_DECLARE | ( | apr_pool_t * | ) |
Get the current owner of the allocator
allocator | The allocator to get the owner from |
APR_DECLARE | ( | apr_size_t | ) |
Get the true size that would be allocated for the given size (including the header and alignment).
allocator | The allocator from which to the memory would be allocated |
size | The size to align |
APR_DECLARE | ( | apr_status_t | ) |
Create a new allocator
allocator | The allocator we have just created. |
APR_DECLARE | ( | void | ) |
Destroy an allocator
allocator | The allocator to be destroyed |
Free a list of blocks of mem, giving them back to the allocator. The list is typically terminated by a memnode with its next field set to NULL.
allocator | The allocator to give the mem back to |
memnode | The memory node to return |
Set the owner of the allocator
allocator | The allocator to set the owner for |
pool | The pool that is to own the allocator |
Set the current threshold at which the allocator should start giving blocks back to the system.
allocator | The allocator to set the threshold on |
size | The threshold. 0 == unlimited. |
