* The Solana runtime provides a memory region that is available to programs at
|
||||||
|
* a fixed virtual address and length. The builtin functions `sol_calloc` and
|
||||||
|
* `sol_free` call into the Solana runtime to allocate from this memory region
|
||||||
|
* for heap operations. Because the memory region is directly available to
|
||||||
|
* programs another option is a program can implement their own heap directly on
|
||||||
|
* top of that region. If a program chooses to implement their own heap they
|
||||||
|
* should not call the builtin heap functions because they will conflict.
|
||||||
|
* `HEAP_START_ADDRESS` and `HEAP_LENGTH` specify the memory region's start
|
||||||
|
* virtual address and length.
