(PECL win32service >=0.1.0)

win32_start_service_ctrl_dispatcher — Registers the script with the SCM, so that it can act as the service with the given name

Descrizione

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.

Attenzione

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