KVMAllocator is a virtual memory allocator.
Memory is allocated block-wise in a tmp file.
KVMAllocator ()
| KVMAllocator |
Create a KVMAllocator
~KVMAllocator ()
| ~KVMAllocator |
Destruct the KVMAllocator and release all memory.
Block * allocate (size_t _size)
| allocate |
Allocate a virtual memory block.
Parameters:
| _size | Size in bytes of the memory block.
|
Returns: the allocated memory block
void free (Block *block)
| free |
Free a virtual memory block.
Parameters:
void copy (void *dest, Block *src, int _offset = 0, size_t length = 0)
| copy |
Copy length bytes from _offset in the virtual memory block
src to normal memory at address *dest.
Parameters:
| dest | the destination of the data
|
| src | the source block
|
| _offset | the offset in the source block
|
| length | the length of the data to copy
|
void copy (Block *dest, void *src, int _offset = 0, size_t length = 0)
| copy |
Copy length bytes from normal memory at address src to
_offset in the virtual memory block dest.
Parameters:
| dest | the block to copy the data to
|
| src | the source location of the data
|
| _offset | the offset in the destination block
|
| length | the length of the data to copy
|
void * map (Block *block)
| map |
Map a virtual memory block in memory
Parameters:
void unmap (Block *block)
| unmap |
Unmap a virtual memory block
