HH\Lib\IO\ReadHandle::readAllAsync

Meta Engineer?

The containing class is available as IO\ReadHandle in the www repository.

Read until there is no more data to read

public function readAllAsync(
  ?int $max_bytes = NULL,
  ?int $timeout_ns = NULL,
): Awaitable<string>;

It is possible for this to never return, e.g. if called on a pipe or or socket which the other end keeps open forever. Set a timeout if you do not want this to happen.

Up to $max_bytes may be allocated in a buffer; large values may lead to unnecessarily hitting the request memory limit.

Parameters

  • ?int $max_bytes = NULL
  • ?int $timeout_ns = NULL

Returns
