win32_start_service_ctrl_dispatcher

(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

说明

win32_start_service_ctrl_dispatcher ( string $name [, bool $gracefulMode = true ] ) : mixed

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.

Caution

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

参数

name

gracefulMode

TRUE for exit graceful. FALSE for exit with error. See win32_set_service_exit_mode() for more details.

返回值

成功时返回 TRUE，参数错误时返回 FALSE，或失败时返回一个 Win32 错误码。

错误／异常

If SAPI is not "cli", this function emits an E_ERROR level error.

// Some lengthy process to get this service up and running.

win32_set_service_status(WIN32_SERVICE_RUNNING);

while (WIN32_SERVICE_CONTROL_STOP != win32_get_last_control_message()) {
