* @brief Take a chunk of memory and add it to the available heap
|
|
* @note Memory added must obviously not already be on the heap.
|
|
* @note It is allowable to add multiple non-contiguous blocks of memory
|
|
* to the heap. If however it is contiguous with a previously added block
|
|
* it will get merged with the existing block in order to allow
|
|
* allocations that span the boundary.
|
|
* @pre GFX_OS_HEAP_SIZE != 0 and an operating system that uses the
|
|
* internal ugfx heap allocator rather than its own allocator.
