Queries the status of a service

win32_query_service_status ( string $servicename [, string $machine ] ) : mixed

Queries the current status for a service, returning an array of information.

servicename: The short name of the service.
machine: The optional machine name. If omitted, the local machine will be used.

Returns an array consisting of the following information on success，参数错误时返回 FALSE，或失败时返回一个 Win32 错误码。

ServiceType: The dwServiceType. See Win32Service Service Type Bitmasks.
CurrentState: The dwCurrentState. See Win32Service Service Status Constants.
ControlsAccepted: Which service controls are accepted by the service. See Win32Service Service Control Message Accepted Bitmasks.
Win32ExitCode: If the service exited, the return code from the process.
ServiceSpecificExitCode: If the service exited with an error condition, the service specific code that is logged in the event log is visible here.
CheckPoint: If the service is shutting down, holds the current check point number. This is used by the SCM as a kind of heart-beat to detect a wedged service process. The value of the check point is best interpreted in conjunction with the WaitHint value.
WaitHint: If the service is shutting down it will set WaitHint to a checkpoint value that will indicate 100% completion. This can be used to implement a progress indicator.
ProcessId: The Windows process identifier. If 0, the process is not running.
ServiceFlags: The dwServiceFlags. See Win32Service Service Service Flag Constants.
