Detailed Description

A RAII wrapper around Microsoft Windows HANDLE.

This class is a movable, non-copyable RAII wrapper on HANDLE.

Constructor & Destructor Documentation

virtual fsw::win_handle::~win_handle ( )

virtual

Destructs a handle.

If the handle is valid (is_valid()) it is closed invoking CloseHandle().

See also

is_valid(const HANDLE &)

fsw::win_handle::win_handle ( win_handle &&  other )

noexcept

Move constructor.

The move constructors moves the handle value wrapped by other to the target instance. The handle value in other is set to INVALID_HANDLE_VALUE. The previously wrapped instance is closed invoking CloseHandle if it is valid.

Parameters

other

The handle to move.

Member Function Documentation

static bool fsw::win_handle::is_valid ( const HANDLE &  handle )

static

Checks whether handle is valid.

A handle is valid is if its value is not null and if is not INVALID_HANDLE_VALUE.

Parameters

handle

The handle to check.

Returns

Returns true if handle is valid, false otherwise.

bool fsw::win_handle::is_valid

(

)

const

Checks whether the handle is valid.

Returns

Returns true if the handle is valid, false otherwise.

See also

is_valid()

win_handle& fsw::win_handle::operator= ( win_handle &&  other )

noexcept

Move assignment operator.

The move assignment operator moves the handle value wrapped by other to the target instance. The handle value in other is set to INVALID_HANDLE_VALUE. The previously wrapped instance is closed invoking CloseHandle if it is valid.

Parameters

other

The handle to move.

win_handle& fsw::win_handle::operator=

(

const HANDLE &

handle

)

Assigns a handle to the current instance.

The previously wrapped instance is closed invoking CloseHandle if it is valid.

Parameters

handle

The handle value to assign to the current instance.
