基于Visual C++之Windows核心编程代码分析（2）实现Windows用户

1、基于visual c+之windows核心编程代码分析（2）实现windows用户在windows编程中间，我们常常需要添加用户，删除用户，添加用户组等等功能，那些功能如何实现呢，我们请见实现代码与注释分析 /* unicode */ ifndef unicode define unicode endif /* 头文件 */ ilude stdio.h include assert.h include windows.h include lm.h /* * auser * 功能 增强用户 * 参数 szservername，主机名，假如为本机增强用户，设置为null * szusername，

2、用户名 * szpassword，密码 */ int adduser(lpwstr szservername, lpwstr szusername, lpwstr szpassword) user_info_1 ui; dword dwlevel = 1; / 用法 user_info_1 作为参数 dword dwerror = 0; net_api_status nstatus; / 填充 user_info_1 ui.usri1_name = szusername; / 用户名 ui.usri1_password = szpassword; / 密码 ui.usri1_priv = us

3、er_priv_user; / privilege ui.usri1_home_dir = null; ui.usri1_comment = null; ui.usri1_flags = uf_script; ui.usri1_script_path = null; / 调用 netuseradd 增强用户 nstatus = netuseradd(szservername, dwlevel, (lpbyte) ui, dwerror); / 推断结果 if (nstatus = nerr_success) wprintf(stderr, l user %s has been ccessful

4、ly add on %sn , szusername, szservername); ee fprintf(stderr, a system error has occurred: %dn , nstatus); return 0; /* * addusertogroup * 功能 为用户组增强用户 * 参数 szservername，主机名，假如为本机，设置为null * szusername，用户名 * szgroup，用户组名 */ int addusertogroup(lpwstr szservername, lpwstr szusername, lpwstr szgroup) net

5、_api_status nstatus; / 调用 netgroupadduser nstatus = netgroupadduser( szservername, szgroup, szusername / 推断结果 if (nstatus = nerr_success) fwprintf(stderr, l user %s has been successfully added on %sn , szusername, szservername); else fprintf(stderr, netgroupadduser a system error has occurred: %dn ,

6、 nstatus); return 0; /* * deluser * 功能 删除用户 * 参数 szservername，主机名，假如为本机，设置为null * szusername，用户名 */ int deluser(lpwstr szservername, lpwstr szusername) dword dwerror = 0; net_api_status nstatus; / 调用 netuserdel 删除用户 nstatus = netuserdel(szservername, szusername); / 推断并显示结果 if (nstatus = nerr_success

7、) fwprintf(stderr, l user %s has been successfully deleted on %sn , szusername, szservername); else fprintf(stderr, a system error has occurred: %dn , nstatus); return 0; /* * int listusers(lpwstr pszservername) * 功能 列举用户 * 参数 szservername，主机名，假如为本机，设置为null */ int listusers(lpwstr pszservername) lpu

8、ser_info_0 pbuf = null; lpuser_info_0 ptmpbuf; dword dwlevel = 0; dword dwprefmaxlen = max_preferred_length; dword dweniesread = 0; dword dwtotalentries = 0; dword dwresumehandle = 0; dword i; dword dwtotalcount = 0; net_api_status nstatus; / 循环，直到可以胜利调用 netuserenum / 调用netuserenum函数 nstatus = netus

9、erenum(pszservername, dwlevel,/ 这里设置为0，用法 lpuser_info_0 返回结果 filter_normal_account, / 只列举“正常”类型的用户 (lpbyte*) pbuf,/ lpuser_info_0 保存返回结果 / max_preferred_length，内存由api分配，需要在之后调用netapibufferfree释放 dwprefmaxlen, dwentriesread,/ 读了的 entries dwtotalentries,/ 一共的 entries dwresumehandle); / 推断是否胜利 if (nsta

10、tus = nerr_success) | (nstatus = error_more_data) if (ptmpbuf = pbuf) != null) / 循环读取用户信息 for (i = 0; (i dwentriesread); i+) assert(ptmpbuf != null); if (ptmpbuf = null) fprintf(stderr, an access violation has occurredn break; / 输出 wprintf(l t- %sn , ptmpbuf- usri0_name); / 下一个 ptmpbuf+; dwtotalcoun

11、t+; else fprintf(stderr, a system error has occurred: %dn , nstatus); / 释放内存 if (pbuf != null) netapibufferfree(pbuf); pbuf = null; while (nstatus = error_more_data); / end do / 释放内存 if (pbuf != null) netapibufferfree(pbuf); fprintf(stderr, total of %d usersnn , dwtotalcount); return 0; /* * int listgroup(lpwstr pszservername) * 功能 列举用户组 * 参数 szservername，主机名，假如为本机，设置为null */ int listgroup(lpwstr pszservername) dword dwlevel = 0; dword
