You can also use the WNetEnumResource function to retrieve resource information. However, WNetEnumResource does not enumerate hidden shares or users connected to a share. Syntax C++ NET_API_STATUS NetShareEnum( __in LPWSTR servername, __in DWORD level, __out LPBYTE *bufptr, __in DWORD prefmaxlen, __out LPDWORD entriesread, __out LPDWORD totalentries, __inout LPDWORD resume_handle ); Parameters servername [in] Pointer to a 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. level [in] Specifies the information level of the data. This parameter can be one of the following values. ValueMeaning 0Return share names. The bufptr parameter points to an array of SHARE_INFO_0 structures. 1Return information about shared resources, including the name and type of the resource, and a comment associated with the resource. The bufptr parameter points to an array of SHARE_INFO_1 structures. 2Return information about shared resources, including name of the resource, type and permissions, password, and number of connections. The bufptr parameter points to an array of SHARE_INFO_2 structures. 502Return information about shared resources, including name of the resource, type and permissions, number of connections, and other pertinent information. The bufptr parameter points to an array of SHARE_INFO_502 structures. Shares from different scopes are not returned. For more information about scoping, see the Remarks section of the documentation for the NetServerTransportAddEx function. 503Return information about shared resources, including the name of the resource, type and permissions, number of connections, and other pertinent information. The bufptr parameter points to an array of SHARE_INFO_503 structures. Shares from all scopes are returned. If the shi503_servername member of this structure is "*", there is no configured server name and the NetShareEnum function enumerates shares for all the unscoped names. Windows Server 2003, Windows XP, Windows 2000 Server, and Windows 2000 Professional: This information level is not supported. 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. Note that you must free the buffer even if the function fails with ERROR_MORE_DATA. prefmaxlen [in] Specifies the preferred maximum length of returned data, in bytes. If you specify MAX_PREFERRED_LENGTH, the function allocates the amount of memory required for the data. If you specify another value in this parameter, it can restrict the number of bytes that the function returns. If the buffer size is insufficient to hold all entries, the function returns ERROR_MORE_DATA. For more information, see Network Management Function Buffers and Network Management Function Buffer Lengths . entriesread [out] Pointer to a value that receives the count of elements actually enumerated. totalentries [out] Pointer to a value that receives the total number of entries that could have been enumerated. Note that applications should consider this value only as a hint. resume_handle [in, out] Pointer to a value that contains a resume handle which is used to continue an existing share search. The handle should be zero on the first call and left unchanged for subsequent calls. If resume_handle is NULL, then no resume handle is stored. Return Value If the function succeeds, the return value is NERR_Success. If the function fails, the return value is a system error code. For a list of error codes, see System Error Codes . Remarks This function applies only to Server Message Block (SMB) shares. For other types of shares, such as Distributed File System (DFS) or WebDAV shares, use Windows Networking (WNet) functions , which support all types of shares. For interactive users (users who are logged on locally to the machine), no special group membership is required to execute the NetShareEnum function. For non-interactive users, Administrator, Power User, Print Operator, or Server Operator group membership is required to successfully execute the NetShareEnum function at levels 2, 502, and 503. No special group membership is required for level 0 or level 1 calls. Windows Server 2003, Windows XP, Windows 2000 Server, and Windows 2000 Professional: For all users, Administrator, Power User, Print Operator, or Server Operator group membership is required to successfully execute the NetShareEnum function at levels 2 and 502. To retrieve a value that indicates whether a share is the root volume in a DFS tree structure, you must call the NetShareGetInfo function and specify information level 1005. 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 share functions. For more information, see IADsFileShare . Windows Server 2003 and Windows XP: If you call this function at information level 2 or 502 on a domain controller that is running Active Directory, access is allowed or denied based on the ACL for the securable object. To enable anonymous access, the user Anonymous must be a member of the Pre-Windows 2000-Compatible Access Group. This is because anonymous tokens do not include the Everyone group SID by default. If you call this function at information level 2 or 502 on a member server or workstation, all authenticated users can view the information. Anonymous access is also permitted if the EveryoneIncludesAnonymous policy setting allows anonymous access. For more information about restricting anonymous access, see Security Requirements for the Network Management Functions . For more information on ACLs, ACEs, and access tokens, see Access Control Model . Windows 2000 Server and Windows 2000 Professional: If you call this function at information level 2 or 502 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-Windows 2000-Compatible Access Group to view the information. By default, the Pre-Windows 2000-Compatible Access Group group includes Everyone as a member. This enables anonymous access to the information if the system allows anonymous access. If you call this function at information level 2 or 502 on a member server or workstation, all authenticated users can view the information. Anonymous access is also permitted if the RestrictAnonymous policy setting allows anonymous access. For more information, see Allowing Anonymous Access . Examples The following code sample demonstrates how to retrieve information about each shared resource on a server using a call to the NetShareEnum function. The sample calls NetShareEnum, specifying information level 502 ( SHARE_INFO_502 ). If the call succeeds, the code loops through the entries and prints information about each share. The sample also calls the IsValidSecurityDescriptor function to validate the shi502_security_descriptor member. Finally, the code sample frees the memory allocated for the information buffer. #define UNICODE #include #include #include #pragma comment(lib, "Netapi32.lib") void wmain( int argc, TCHAR *lpszArgv[ ]) { PSHARE_INFO_502 BufPtr,p; NET_API_STATUS res; LPTSTR lpszServer = NULL; DWORD er=0,tr=0,resume=0, i; switch(argc) { case 2: lpszServer = lpszArgv[1]; break; default: printf("Usage: NetShareEnum return; } // // Print a report header. // printf("Share: Local Path: Uses: Descriptor:\\n"); printf("---------------------------------------------------------------------\\n"); // // Call the NetShareEnum function; specify level 502. // do // begin do { res = NetShareEnum (lpszServer, 502, (LPBYTE *) &BufPtr, -1, &er, &tr, &resume); // // If the call succeeds, // if(res == ERROR_SUCCESS || res == ERROR_MORE_DATA) { p=BufPtr; // // Loop through the entries; // print retrieved data. // for(i=1;i<=er;i++) { printf("%-20S%-30S%-8u",p->shi502_netname, p->shi502_path, p->shi502_current_uses); // // Validate the value of the // shi502_security_descriptor member. // if (IsValidSecurityDescriptor(p->shi502_security_descriptor)) printf("Yes\\n"); else printf("No\\n"); p++; } // // Free the allocated buffer. // NetApiBufferFree(BufPtr); } else printf("Error: %ld\\n",res); } // Continue to call NetShareEnum while // there are more entries. // while (res==ERROR_MORE_DATA); // end do return; } Requirements Minimum supported clientWindows 2000 Professional Minimum supported serverWindows 2000 Server HeaderLmshare.h (include Lm.h) LibraryNetapi32.lib DLLNetapi32.dll See Also Network Management Overview Network Management Functions Network Share Functions SHARE_INFO_0 SHARE_INFO_1 SHARE_INFO_2 SHARE_INFO_502 Send comments about this topic to Microsoft Build date: 4/9/2009 ＝＝原始网址＝＝http://msdn.microsoft.com/en-us/library/bb525387(VS.85).aspx\n |
