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::run ( 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.
