Function nstd_alloc_deallocate 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn nstd_alloc_deallocate(
    ptr: NSTDAnyMut,
    layout: NSTDAllocLayout,
) -> NSTDAllocError

Available on crate feature alloc only.

Deallocates memory that was previously allocated by this allocator.

Parameters:

• NSTDAnyMut ptr - A pointer to the allocated memory.

• NSTDAllocLayout layout - Describes the layout of memory that ptr points to.

Returns

NSTDAllocError errc - The allocation operation error code.

Safety

• Behavior is undefined if ptr is not a pointer to memory allocated by this allocator.

• layout must be the same value that was used to allocate the memory buffer.

Example

use nstd_sys::{
    alloc::{nstd_alloc_allocate, nstd_alloc_deallocate},
    core::alloc::{nstd_core_alloc_layout_new, NSTDAllocError::NSTD_ALLOC_ERROR_NONE},
};

unsafe {
    let layout = nstd_core_alloc_layout_new(24, 1).unwrap();
    let mem = nstd_alloc_allocate(layout);
    assert!(!mem.is_null());
    assert!(nstd_alloc_deallocate(mem, layout) == NSTD_ALLOC_ERROR_NONE);
}
