Module windows::core

A type representing an agile reference to a COM/WinRT object.

Array

A WinRT array stores elements contiguously in a heap-allocated buffer.

Borrowed

A logically borrowed type that still retains the in-memory representation of the underlying type.

Error

An error object consists of both an error code as well as detailed error information for debugging.

Event

A type that you can use to declare and implement an event of a specified delegate type.

GUID

A globally unique identifier (GUID) used to identify COM and WinRT interfaces.

HRESULT

An error code value returned by most COM functions.

HSTRING

A WinRT string (HSTRING) is reference-counted and immutable.

IInspectable

A WinRT object that may be used as a polymorphic stand-in for any WinRT class, interface, or boxed value. IInspectable represents the IInspectable interface.

IUnknown

All COM interfaces (and thus WinRT classes and interfaces) implement IUnknown under the hood to provide reference-counted lifetime management as well as the ability to query for additional interfaces that the object may implement.

InParam

An “IN” param to a Windows API.

PCSTR

A pointer to a constant null-terminated string of 8-bit Windows (ANSI) characters.

PCWSTR

A pointer to a constant null-terminated string of 16-bit Unicode characters.

PSTR

A pointer to a null-terminated string of 8-bit Windows (ANSI) characters.

PWSTR

A pointer to a null-terminated string of 16-bit Unicode characters.

Weak

Weak holds a non-owning reference to an object.
