Struct winsafe::guard::GlobalUnlockGuard

pub struct GlobalUnlockGuard<'a, H>
where
    H: kernel_Hglobal,
{ /* private fields */ }

Available on crate feature kernel only.

RAII implementation for HGLOBAL lock which automatically calls GlobalUnlock when the object goes out of scope.

Implementations

impl<'a, H> GlobalUnlockGuard<'a, H>

where H: kernel_Hglobal,

pub const unsafe fn new(hglobal: &'a H, pmem: *mut c_void, sz: usize) -> Self

Constructs the guard.

Safety

Be sure the handle must be freed with GlobalUnlock at the end of scope, the pointer is valid, and the size is correct.

pub const fn as_ptr(&self) -> *const c_void

Returns a pointer to the allocated memory block, or null if not allocated.

pub fn as_mut_ptr(&mut self) -> *mut c_void

Returns a mutable pointer to the allocated memory block, or null if not allocated.

pub const fn as_slice(&self) -> &[u8]

Returns a slice over the allocated memory block.

pub fn as_mut_slice(&mut self) -> &mut [u8]

Returns a mutable slice over the allocated memory block.

pub const unsafe fn as_slice_aligned<T>(&self) -> &[T]

Returns a slice over the allocated memory block, aligned to the given type.

Safety

Make sure the alignment is correct.

pub unsafe fn as_mut_slice_aligned<T>(&mut self) -> &mut [T]

Returns a mutable slice over the allocated memory block, aligned to the given type.

Safety

Make sure the alignment is correct.

pub const fn len(&self) -> usize

Returns the size of the allocated memory block.

Trait Implementations

impl<'a, H> Drop for GlobalUnlockGuard<'a, H>

where H: kernel_Hglobal,

fn drop(&mut self)

Executes the destructor for this type.
