PHP 7.4.24 Released!

win32_start_service_ctrl_dispatcher

(PECL win32service >=0.1.0)

win32_start_service_ctrl_dispatcherRegisters the script with the SCM, so that it can act as the service with the given name

Beschreibung

win32_start_service_ctrl_dispatcher(string $name, bool $gracefulMode = true): void

When launched via the Service Control Manager, a service process is required to "check-in" with it to establish service monitoring and communication facilities. This function performs the check-in by spawning a thread to handle the lower-level communication with the service control manager.

Once started, the service process should do 2 things. The first is to tell the Service Control Manager that the service is running. This is achieved by calling win32_set_service_status() with the WIN32_SERVICE_RUNNING constant. If you need to perform some lengthy process before the service is actually running, then you can use the WIN32_SERVICE_START_PENDING constant. The second is to continue to check-in with the service control manager so that it can determine if it should terminate. This is achieved by periodically calling win32_get_last_control_message() and handling the return code appropriately.

Achtung

Since version 0.2.0, this function work only in "cli" SAPI. On other SAPI this function is disabled.

Parameter-Liste

name

The short-name of the service, as registered by win32_create_service().

gracefulMode

true for exit graceful. false for exit with error. See win32_set_service_exit_mode() for more details.

Rückgabewerte

Es wird kein Wert zurückgegeben.

Prior to version 1.0.0, gab im Erfolgsfall WIN32_NO_ERROR zurück oder false, wenn es ein Problem mit den Parametern gab oder einen Win32-Fehlercode im Fehlerfall.

Don't try to call "win32_start_service_ctrl_dispatcher" too late in your code. You'd trigger a #2186 error : "The service is not responding to the control function." (from commande line) or a #1053 error : "The service did not respond to the start or control request in a timely fashion." (from services GUI).

Try not to load a bunch of PEAR classes before to register php script as Service like I did.

Another good hint, to get a verbose version of the return code, you can call "NET HELPMSG ###" from command line where ### is your error code.
