nn::fnd::ExpHeapTemplate Classtemplate <class LockPolicy> class ExpHeapTemplate :public nn::fnd::ExpHeapBase
| Name | Description |
|---|---|
| LockPolicy | Specifies the lock policy to use during operations on the heap. |
Class template for the expanded heap.
In classes that instantiate this class template, mutual exclusion is done using the lock policy specified by this function. For the lock policy, you can either specify one of the classes declared within the nn::os::LockPolicy class or specify a class that instantiates the class template. Neither operation nor compatibility is guaranteed if you specify any other class for the LockPolicy argument.
Locking is only performed on operations within the heap. If you want to perform operations on the heap hierarchy, you must take additional appropriate measures to ensure exclusive access.

|---|
ExpHeapTemplate
|
Constructor. | |
|---|---|---|
Initialize
|
Initializes the heap. | |
Invalidate
|
Invalidates the heap. | |
Finalize
|
If the heap is valid, it destroys it. | |
| V |
~ExpHeapTemplate
|
Destructor. Calls Finalize. |
Allocate
|
Allocates memory from the expanded heap. | |
Free
|
Frees a memory block that was allocated from the expanded heap. | |
| V |
FreeV
|
Frees a memory block that was allocated from the expanded heap. |
ResizeBlock
|
Changes the size of a memory block that was allocated from the expanded heap. | |
VisitAllBlocks
|
Calls a user-specified visitor function on all memory blocks that have been allocated from the expanded heap. |
|
| V |
GetStartAddress
|
Gets the starting address of the expanded heap's memory region. |
| V |
GetTotalSize
|
Gets the memory size assigned to the expanded heap. |
GetTotalFreeSize
|
Gets the available memory size of the expanded heap. | |
GetAllocatableSize
|
Gets the size of the memory block that can be allocated from the expanded heap. | |
Adjust
|
Use of this function is NOT recommended. This function frees unused areas at the tail of the expanded heap to reduce the amount of memory the expanded heap uses. | |
CheckHeap
|
Checks whether the expanded heap has been destroyed. | |
CheckBlock
|
Checks memory blocks that have been allocated from the expanded heap. | |
| V |
HasAddress
|
Determines whether the specified address is located within a heap. |
| V |
Dump
|
Displays a heap's internal information. (Used for debugging.) |
| S |
Create
|
Creates an expanded heap within a parent heap. |
