Public Member Functions

 vmemory () noexcept
 Initializes a new class instance with the memory handle set to INVAL.
 
 vmemory (handle_type h, HANDLE proc) noexcept
 Initializes a new class instance with an already available object handle.
 
 vmemory (vmemory &&h) noexcept
 Move constructor.
 
virtual ~vmemory ()
 Frees the memory.
 
vmemoryoperator= (vmemory &&other) noexcept
 Move assignment.
 
void attach (HANDLE proc, handle_type h) noexcept
 Sets a new memory handle for the class.
 
bool alloc (HANDLE hProcess, LPVOID lpAddress, SIZE_T dwSize, DWORD flAllocationType, DWORD flProtect) noexcept
 Reserves, commits, or changes the state of a region of memory within the virtual address space of a specified process. The function initializes the memory it allocates to zero.
 
- Public Member Functions inherited from winstd::handle< LPVOID, NULL >
 handle () noexcept
 Initializes a new class instance with the object handle set to INVAL.
 
 handle (handle_type h) noexcept
 Initializes a new class instance with an already available object handle.
 
 handle (handle< handle_type, INVAL > &&h) noexcept
 Move constructor.
 
handle< handle_type, INVAL > & operator= (handle_type h) noexcept
 Attaches already available object handle.
 
handle< handle_type, INVAL > & operator= (handle< handle_type, INVAL > &&h) noexcept
 Move assignment.
 
 operator handle_type () const
 Auto-typecasting operator.
 
handle_type *& operator* () const

handle_typeoperator& ()
 Returns the object handle reference.
 
handle_type operator-> () const
 Provides object handle member access when the object handle is a pointer to a class or struct.
 
bool operator! () const
 Tests if the object handle is invalid.
 
bool operator< (handle_type h) const
 Is handle less than?
 
bool operator<= (handle_type h) const
 Is handle less than or equal to?

void attach (handle_type h) noexcept
 Sets a new object handle for the class.
 
handle_type detach ()
 Dismisses the object handle from this class.
 
void free ()
 Destroys the object.

Detailed Description

Memory in virtual address space of a process handle wrapper.

Constructor & Destructor Documentation

◆ vmemory() [1/2]

winstd::vmemory::vmemory ( handle_type h,
HANDLE proc )
inlinenoexcept

Initializes a new class instance with an already available object handle.

Parameters
[in]procHandle of process the memory belongs to
[in]hInitial object handle value

◆ vmemory() [2/2]

winstd::vmemory::vmemory ( vmemory && h)
inlinenoexcept

Move constructor.

Parameters
[in,out]hA rvalue reference of another object

◆ ~vmemory()

virtual winstd::vmemory::~vmemory ( )
inlinevirtual

Frees the memory.

See also
VirtualFreeEx function

Member Function Documentation

◆ alloc()

bool winstd::vmemory::alloc ( HANDLE hProcess,
LPVOID lpAddress,
SIZE_T dwSize,
DWORD flAllocationType,
DWORD flProtect )
inlinenoexcept

Reserves, commits, or changes the state of a region of memory within the virtual address space of a specified process. The function initializes the memory it allocates to zero.

See also
VirtualAllocEx function
Returns
  • true when succeeds;
  • false when fails. Use GetLastError() for failure reason.

◆ attach()

void winstd::vmemory::attach ( HANDLE proc,
handle_type h )
inlinenoexcept

Sets a new memory handle for the class.

When the current object handle of the class is non-INVAL, the object is destroyed first.

Parameters
[in]procHandle of process the memory belongs to
[in]hInitial object handle value

◆ free_internal()

void winstd::vmemory::free_internal ( )
inlineoverrideprotectedvirtualnoexcept

Frees the memory.

See also
VirtualFreeEx function

Implements winstd::handle< LPVOID, NULL >.

◆ operator=()

vmemory & winstd::vmemory::operator= ( vmemory && other)
inlinenoexcept

Move assignment.

Parameters
[in,out]otherA rvalue reference of another object
