Function nstd_heap_ptr_drop 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn nstd_heap_ptr_drop(
    hptr: NSTDHeapPtr<'_>,
    callback: unsafe extern "C" fn(NSTDAnyMut),
)

Available on crate feature heap_ptr only.

Frees an instance of NSTDHeapPtr after invoking callback with the heap object’s data.

Parameters:

• NSTDHeapPtr hptr - A pointer to the heap object.

• void (*callback)(NSTDAnyMut) - The heap object’s destructor.

Safety

This operation makes a direct call on a C function pointer (callback).
