# 定義済み定数

以下の定数が定義されています。 この関数の拡張モジュールが PHP 組み込みでコンパイルされているか、 実行時に動的にロードされている場合のみ使用可能です。

Return values. Always check GearmanClient::error or GearmanWorker for a string error, as it may contain more details:

`GEARMAN_SUCCESS` ( integer )
  Whatever action was taken was successful.
`GEARMAN_IO_WAIT` ( integer )
  When in non-blocking mode, an event is hit that would have blocked.
`GEARMAN_ERRNO` ( integer )
  A system error. Check GearmanClient::errno or GearmanWorker::errno for the system error code that was returned.
`GEARMAN_NO_ACTIVE_FDS` ( integer )
  GearmanClient::wait or GearmanWorker was called with no connections.
`GEARMAN_UNEXPECTED_PACKET` ( integer )
  Indicates something going very wrong in gearmand. Applies only to GearmanWorker.
`GEARMAN_GETADDRINFO` ( integer )
  DNS resolution failed (invalid host, port, etc).
`GEARMAN_NO_SERVERS` ( integer )
  Did not call GearmanClient::addServer before submitting jobs or tasks.
`GEARMAN_LOST_CONNECTION` ( integer )
  Lost a connection during a request.
`GEARMAN_MEMORY_ALLOCATION_FAILURE` ( integer )
  Memory allocation failed (ran out of memory).
`GEARMAN_SERVER_ERROR` ( integer )
  Something went wrong in the Gearman server and it could not handle the request gracefully.
`GEARMAN_WORK_DATA` ( integer )
  Notice return code obtained with GearmanClient::returnCode when using GearmanClient::do. Sent to update the client with data from a running job. A worker uses this when it needs to send updates, send partial results, or flush data during long running jobs.
`GEARMAN_WORK_WARNING` ( integer )
  Notice return code obtained with GearmanClient::returnCode when using 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` ( integer )
  Notice return code obtained with GearmanClient::returnCode when using GearmanClient::do. Sent to update the status of a long running job. Use GearmanClient::doStatus to obtain the percentage complete of the task.
`GEARMAN_WORK_EXCEPTION` ( integer )
  Notice return code obtained with GearmanClient::returnCode when using GearmanClient::do. Indicates that a job failed with a given exception.
`GEARMAN_WORK_FAIL` ( integer )
  Notice return code obtained with GearmanClient::returnCode when using GearmanClient::do. Indicates that the job failed.
`GEARMAN_COULD_NOT_CONNECT` ( integer )
  Failed to connect to servers.
`GEARMAN_INVALID_FUNCTION_NAME` ( integer )
  Trying to register a function name of NULL or using the callback interface without specifying callbacks.
`GEARMAN_INVALID_WORKER_FUNCTION` ( integer )
  Trying to register a function with a NULL callback function.
`GEARMAN_NO_REGISTERED_FUNCTIONS` ( integer )
  When a worker gets a job for a function it did not register.
`GEARMAN_NO_JOBS` ( integer )
  For a non-blocking worker, when GearmanWorker::work does not have any active jobs.
`GEARMAN_ECHO_DATA_CORRUPTION` ( integer )
  After GearmanClient::echo or GearmanWorker::echo the data returned doesn't match the data sent.
`GEARMAN_NEED_WORKLOAD_FN` ( integer )
  When the client opted to stream the workload of a task, but did not specify a workload callback function.
`GEARMAN_PAUSE` ( integer )
  For the non-blocking client task interface, can be returned from the task callback to "pause" the call and return from GearmanClient::runTasks. Call GearmanClient::runTasks again to continue.
`GEARMAN_UNKNOWN_STATE` ( integer )
  Internal client/worker state error.
`GEARMAN_SEND_BUFFER_TOO_SMALL` ( integer )
  Internal error: trying to flush more data in one atomic chunk than is possible due to hard-coded buffer sizes.
`GEARMAN_TIMEOUT` ( integer )
  Hit the timeout limit set by the client/worker.

GearmanClient options:

`GEARMAN_CLIENT_NON_BLOCKING` ( integer )
  Run the cient in a non-blocking mode.
`GEARMAN_CLIENT_UNBUFFERED_RESULT` ( integer )
  Allow the client to read data in chunks rather than have the library buffer the entire data result and pass that back.
`GEARMAN_CLIENT_FREE_TASKS` ( integer )
  Automatically free task objects once they are complete. This is the default setting in this extension to prevent memory leaks.

GearmanWorker options:

`GEARMAN_WORKER_NON_BLOCKING` ( integer )
  Run the worker in non-blocking mode.
`GEARMAN_WORKER_GRAB_UNIQ` ( integer )
  Return the client assigned unique ID in addition to the job handle.

Base Gearman configuration:

`GEARMAN_DEFAULT_TCP_HOST` ( string )
`GEARMAN_DEFAULT_TCP_PORT` ( integer )
`GEARMAN_DEFAULT_SOCKET_TIMEOUT` ( integer )
`GEARMAN_DEFAULT_SOCKET_SEND_SIZE` ( integer )
`GEARMAN_DEFAULT_SOCKET_RECV_SIZE` ( integer )
`GEARMAN_MAX_ERROR_SIZE` ( integer )
`GEARMAN_PACKET_HEADER_SIZE` ( integer )
`GEARMAN_JOB_HANDLE_SIZE` ( integer )
`GEARMAN_OPTION_SIZE` ( integer )
`GEARMAN_UNIQUE_SIZE` ( integer )
`GEARMAN_MAX_COMMAND_ARGS` ( integer )
`GEARMAN_ARGS_BUFFER_SIZE` ( integer )
`GEARMAN_SEND_BUFFER_SIZE` ( integer )
`GEARMAN_RECV_BUFFER_SIZE` ( integer )
`GEARMAN_WORKER_WAIT_TIMEOUT` ( integer )
