Function nstd_heap_ptr_get 

#[unsafe(no_mangle)]
pub const extern "C" fn nstd_heap_ptr_get(
    hptr: &NSTDHeapPtr<'_>,
) -> NSTDAny

Available on crate feature heap_ptr only.

Returns an immutable raw pointer to the object on the heap.

Note

This will always return null if the size of the object being stored on the heap is 0.

Parameters:

• const NSTDHeapPtr *hptr - The heap pointer.

Returns

NSTDAny ptr - A raw pointer to the object on the heap.

Example

use core::ptr::addr_of;
use nstd_sys::{
    alloc::NSTD_ALLOCATOR,
    core::alloc::nstd_core_alloc_layout_new,
    heap_ptr::{nstd_heap_ptr_get, nstd_heap_ptr_new},
};

unsafe {
    let v = -46923i128;
    let size = core::mem::size_of::<i128>();
    let align = core::mem::align_of::<i128>();
    let layout = nstd_core_alloc_layout_new(size, align).unwrap();
    let hptr = nstd_heap_ptr_new(&NSTD_ALLOCATOR, layout, addr_of!(v).cast()).unwrap();
    assert!(*nstd_heap_ptr_get(&hptr).cast::<i128>() == v);
