Function nstd_sys::shared_ptr::nstd_shared_ptr_size

#[no_mangle]
pub const extern "C" fn nstd_shared_ptr_size(
    shared_ptr: &NSTDSharedPtr<'_>
) -> NSTDUInt

Available on crate feature shared_ptr only.

Returns the size of the shared object.

Parameters:

• const NSTDSharedPtr *shared_ptr - The shared pointer.

Returns

NSTDUInt size - The size of the shared object.

Example

use nstd_sys::{
    alloc::NSTD_ALLOCATOR,
    core::alloc::nstd_core_alloc_layout_new,
    shared_ptr::{nstd_shared_ptr_new_zeroed, nstd_shared_ptr_size},
};

unsafe {
    let size = core::mem::size_of::<f64>();
    let align = core::mem::align_of::<f64>();
    let layout = nstd_core_alloc_layout_new(size, align).unwrap();
    let shared_ptr = nstd_shared_ptr_new_zeroed(&NSTD_ALLOCATOR, layout).unwrap();
    assert!(nstd_shared_ptr_size(&shared_ptr) == size);
