Dex.Future.await

### Method

# Dex Futureawait

#### Declaration [src]

    gboolean
    dex_await (
      DexFuture* future
      GError** error
    )

#### Description [src]

Suspends the current `DexFiber` and resumes when `future` has completed.

If `future` is completed when this function is called, the fiber will handle the result immediately.

This function may only be called within a `DexFiber`. To do otherwise will return `FALSE` and `error` set to `DEX_ERROR_NO_FIBER`.

It is an error to call this function in a way that would cause intermediate code to become invalid when resuming the stack. For example, if a foreach-style function taking a callback was to suspend from the callback, undefined behavior may occur such as thread-local-storage having changed.

#### Return value

Type: `gboolean`

`TRUE` if the future resolved, otherwise `FALSE` and `error` is set.
