这是在学习windows的服务安装机制时的笔记，主要是一些函数的说明，还有我自己的代码，没有整理过比较乱
OpenSCManager：
The OpenSCManager function establishes a connection to the service control manager on the specified computer and opens the specified service control manager database.
SC_HANDLE OpenSCManager(
LPCTSTR lpMachineName,
LPCTSTR lpDatabaseName,
DWORD dwDesiredAccess 如果以administrators的权限创建服务的话，该字段的值为SC_MANAGER_ALL_ACCESS
);
CreateService：
The CreateService function creates a service object and adds it to the specified service control manager database
SC_HANDLE CreateService(
SC_HANDLE hSCManager,
LPCTSTR lpServiceName, //服务的名称
LPCTSTR lpDisplayName,
DWORD dwDesiredAccess, //SERVICE_ALL_ACCESS
DWORD dwServiceType, //SERVICE_WIN32_OWN_PROCESS
DWORD dwStartType, //SERVICE_AUTO_START
DWORD dwErrorControl, //SERVICE_ERROR_IGNORE
LPCTSTR lpBinaryPathName, //指向二进制文件的路径
LPCTSTR lpLoadOrderGroup,
LPDWORD lpdwTagId,
LPCTSTR lpDependencies,
LPCTSTR lpServiceStartName,
LPCTSTR lpPassword
);
Type Meaning
SERVICE_FILE_SYSTEM_DRIVER File system driver service.
SERVICE_KERNEL_DRIVER Driver service.
SERVICE_WIN32_OWN_PROCESS Service that runs in its own process.
SERVICE_WIN32_SHARE_PROCESS Service that shares a process with other services.
StartService： 启动一个服务
BOOL StartService(
SC_HANDLE hService,
DWORD dwNumServiceArgs,
LPCTSTR* lpServiceArgVectors
);
QueryServiceStatus：
BOOL QueryServiceStatus(
SC_HANDLE hService,
LPSERVICE_STATUS lpServiceStatus
);
Return:
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
RegisterServiceCtrlHandler: 注册一个服务
SERVICE_STATUS_HANDLE RegisterServiceCtrlHandler(
LPCTSTR lpServiceName, //服务的名字
LPHANDLER_FUNCTION lpHandlerProc //服务的控制函数的名字
);
创建服务线程 服务完成的功能在这里调用
CreateThread
HANDLE CreateThread(
LPSECURITY_ATTRIBUTES lpThreadAttributes,
SIZE_T dwStackSize,
LPTHREAD_START_ROUTINE lpStartAddress, //线程函数的名字
LPVOID lpParameter,
DWORD dwCreationFlags,
LPDWORD lpThreadId
);
附上我的代码：
#include "windows.h"
#include "stdio.h"
//全局变量
SERVICE_STATUS ServiceStatus;
SERVICE_STATUS_HANDLE ServiceStatusHandle;
//函数声明

{
//定义SERVICE_TABLE_ENTRY DispatchTable[] 结构
SERVICE_TABLE_ENTRY DispatchTable[2] =
{
{"mixu_yy", ServiceStart},
{NULL, NULL}
};
//安装或者打开服务
StartServiceCtrlDispatcher(DispatchTable);
InstallService(argv[0]);
return 0;
