Syntax C++ NET_API_STATUS NetUserModalsGet( __in LPCWSTR servername, __in DWORD level, __out LPBYTE *bufptr ); Parameters servername [in] Pointer to a constant string that specifies the DNS or NetBIOS name of the remote server on which the function is to execute. If this parameter is NULL, the local computer is used. For more information, see the following Remarks section. level [in] Specifies the information level of the data. This parameter can be one of the following values. ValueMeaning 0Return global password parameters. The bufptr parameter points to a USER_MODALS_INFO_0 structure. 1Return logon server and domain controller information. The bufptr parameter points to a USER_MODALS_INFO_1 structure. 2Return domain name and identifier. The bufptr parameter points to a USER_MODALS_INFO_2 structure. For more information, see the following Remarks section. 3Return lockout information. The bufptr parameter points to a USER_MODALS_INFO_3 structure. A null session logon can call NetUserModalsGet anonymously at information levels 0 and 3. bufptr [out] Pointer to the buffer that receives the data. The format of this data depends on the value of the level parameter. This buffer is allocated by the system and must be freed using the NetApiBufferFree function. For more information, see Network Management Function Buffers and Network Management Function Buffer Lengths . Return Value If the function succeeds, the return value is NERR_Success. If the function fails, the return value can be one of the following error codes. Return codeDescription ERROR_ACCESS_DENIEDThe user does not have access to the requested information. NERR_InvalidComputerThe computer name is invalid. Remarks If you are programming for Active Directory, you may be able to call certain Active Directory Service Interface (ADSI) methods to achieve the same functionality you can achieve by calling the network management user modal functions. For more information, see IADsDomain . If you call this function on a domain controller that is running Active Directory, access is allowed or denied based on the access control list (ACL) for the securable object . The default ACL permits all authenticated users and members of the " Pre-Windows2000 compatible access " group to view the information. If you call this function on a member server or workstation, all authenticated users can view the information. For information about anonymous access and restricting anonymous access on these platforms, see Security Requirements for the Network Management Functions . For more information on ACLs, ACEs, and access tokens, see Access Control Model . The security descriptor of the Domain object is used to perform the access check for this function. To retrieve the security identifier (SID) of the domain to which the computer belongs, call the NetUserModalsGet function specifying a USER_MODALS_INFO_2 structure and NULL in the servername parameter. If the computer isn't a member of a domain, the function returns a NULL pointer. Examples The following code sample demonstrates how to retrieve global information for all users and global groups with a call to the NetUserModalsGet function. The sample calls NetUserModalsGet, specifying information level 0 ( USER_MODALS_INFO_0 ). If the call succeeds, the sample prints global password information. Finally, the code sample frees the memory allocated for the information buffer. #ifndef UNICODE #define UNICODE #endif #pragma comment(lib, "netapi32.lib") #include #include #include int wmain(int argc, wchar_t *argv[]) { DWORD dwLevel = 0; USER_MODALS_INFO_0 *pBuf = NULL; NET_API_STATUS nStatus; LPTSTR pszServerName = NULL; if (argc > 2) { fwprintf(stderr, L"Usage: %s [\\\\\\\\ServerName]\\n", argv[0]); exit(1); } // The server is not the default local computer. // if (argc == 2) pszServerName = (LPTSTR) argv[1]; // // Call the NetUserModalsGet function; specify level 0. // nStatus = NetUserModalsGet((LPCWSTR) pszServerName, dwLevel, (LPBYTE *)&pBuf); // // If the call succeeds, print the global information. // if (nStatus == NERR_Success) { if (pBuf != NULL) { printf("\\tMinimum password length: %d\\n", pBuf->usrmod0_min_passwd_len); printf("\\tMaximum password age (d): %d\\n", pBuf->usrmod0_max_passwd_age/86400); printf("\\tMinimum password age (d): %d\\n", pBuf->usrmod0_min_passwd_age/86400); printf("\\tForced log off time (s): %d\\n", pBuf->usrmod0_force_logoff); printf("\\tPassword history length: %d\\n", pBuf->usrmod0_password_hist_len); } } // Otherwise, print the system error. // else fprintf(stderr, "A system error has occurred: %d\\n", nStatus); // // Free the allocated memory. // if (pBuf != NULL) NetApiBufferFree(pBuf); return 0; } Requirements Minimum supported clientWindows 2000 Professional Minimum supported serverWindows 2000 Server HeaderLmaccess.h (include Lm.h) LibraryNetapi32.lib DLLNetapi32.dll See Also Network Management Overview Network Management Functions User Modals Functions NetUserModalsSet USER_MODALS_INFO_0 USER_MODALS_INFO_1 USER_MODALS_INFO_2 USER_MODALS_INFO_3 Send comments about this topic to Microsoft Build date: 8/13/2009 ＝＝原始网址＝＝http://msdn.microsoft.com/en-us/library/aa370656(VS.85).aspx\n |
