Static Public Member Functions
template<typename F>

static std::shared_ptr< Once >	create (Args &&...args)
	Creates a new resource of the given type.

Additional Inherited Members
Public Member Functions inherited from uvw::UnderlyingType< Once, uv_once_t >
Loop &	loop () const noexcept
	Gets the loop from which the resource was originated.

const uv_once_t *	raw () const noexcept
	Gets the underlying raw data structure.

uv_once_t *	raw () noexcept
	Gets the underlying raw data structure.

Detailed Description

The Once wrapper.

Runs a function once and only once. Concurrent calls to once will block all callers except one (it’s unspecified which one).

Member Function Documentation

template<typename F>

static void uvw::Once::once ( F && f )

inlinestaticnoexcept

Runs a function once and only once.

The callback must be such that it's convertible to void(*)(void). Free functions and non-capturing lambdas are both viable solutions.

Template Parameters

F	Type of the callback.

Parameters

f	A valid callback function.
