Create a Foxit manager from a pre-allocated, fixed memory buffer.

This form of Foxit manager is typically used on embedded systems where memory is limited and can be dedicated to single task. The application is responsible to allocate and free the fixed memory buffer. Buffer size can't be lower than 512KB, there is no upper limit. Now the fixed memory manager supports extensible pool. If parameter pExtender is not NULL, then when current memory pool runs out, it will ask for more from the system.

Parameters

  [in] | pMemory | A pointer to a memory block.
  [in] | size | The size in bytes of the memory block pointed by parameter pMemory.
  [in] | pExtender | A pointer to a FXMEM_SystemMgr2 object.

## ◆ FXMEM_CreateFoxitMgr()

FXMEM_FoxitMgr* FXMEM_CreateFoxitMgr | ( | FXMEM_SystemMgr * | pSystemMgr | ) |

On desktop platforms, you don't have to create a Foxit manager to use memory allocation, because FPDFAPI comes with a default Foxit manager (and underlying default system manager). But if your application uses non-default system manager, you will have to create a new Foxit manager that makes use of the custom system manager.

Parameters

  [in] | pSystemMgr | A pointer to a FXMEM_SystemMgr object.

Returns
  A pointer to a FXMEM_FoxitMgr object.

## ◆ FXMEM_CreateMemoryMgr()

FXMEM_FoxitMgr* FXMEM_CreateMemoryMgr | ( | size_t | size,
|  | FX_BOOL | extensible
| ) |  |

Parameters

  [in] | size | Initial size of memory pool, in bytes. It should be not less than 8MB(1024 * 1024 * 8).
  [in] | extensible | If it's true, memory pool will extend if need more space. And false means memory cannot be extended.

Returns
  A pointer to a FXMEM_FoxitMgr object.

Note
  If parameter extensible is false and there is no enough space to allocate, FX_Alloc or FX_Realloc will return NULL directly. For extensible memory manager, it will try to request more memory pools to allocate.

Create a Python manager. A fast, special-purpose memory allocator for small blocks, to be used on top of a general-purpose malloc – heavily based on previous art.

On desktop platforms, you don't have to create a Foxit manager to use memory allocation, because FPDFAPI comes with a default Foxit manager (and underlying default system manager). But if your application uses non-default system manager, you can create a new Python manager that makes use of the custom system manager.

Returns
  A pointer to a FXMEM_FoxitMgr object.
