GEARMAN_NO_ACTIVE_FDS (int)
<span class="methodname">GearmanClient::wait or <span class="methodname">GearmanWorker was called with no connections.

GEARMAN_UNEXPECTED_PACKET (int)

A worker uses this when it needs to send updates, send partial results, or flush data during long running jobs.

GEARMAN_WORK_WARNING (int)
Notice return code obtained with <span class="methodname">GearmanClient::returnCode when using <span class="methodname">GearmanClient::do. Updates the client with a warning. The behavior is just like GEARMAN_WORK_DATA, but should be treated as a warning instead of normal response data.

GEARMAN_WORK_STATUS (int)
Notice return code obtained with <span class="methodname">GearmanClient::returnCode when using <span class="methodname">GearmanClient::do. Sent to update the status of a long running job. Use <span class="methodname">GearmanClient::doStatus to obtain the percentage complete of the task.

GEARMAN_WORK_EXCEPTION (int)

GEARMAN_NEED_WORKLOAD_FN (int)
When the client opted to stream the workload of a task, but did not specify a workload callback function.

GEARMAN_PAUSE (int)
For the non-blocking client task interface, can be returned from the task callback to "pause" the call and return from GearmanClient::runTasks. Call <span class="methodname">GearmanClient::runTasks again to continue.

GEARMAN_UNKNOWN_STATE (int)
Internal client/worker state error.

GEARMAN_SEND_BUFFER_TOO_SMALL (int)
Internal error: trying to flush more data in one atomic chunk than is possible due to hard-coded buffer sizes.
