[Microsoft strongly recommends developers utilize alternative means to achieve your application’s needs. Many scenarios that TxF was developed for can be achieved through simpler and more readily available techniques. Furthermore, TxF may not be available in future versions of Microsoft Windows. For more information, and alternatives to TxF, please see Alternatives to using Transactional NTFS.]
Retrieves the full path and file name of the specified file as a transacted operation.
To perform this operation without transactions, use the GetFullPathName function.
For more information about file and path names, see File Names, Paths, and Namespaces.
DWORD GetFullPathNameTransactedA( LPCSTR lpFileName, DWORD nBufferLength, LPSTR lpBuffer, LPSTR *lpFilePart, HANDLE hTransaction );
The name of the file.
This string can use short (the 8.3 form) or long file names. This string can be a share or volume name.
The file must reside on the local computer; otherwise, the function fails and the last error code is set to ERROR_TRANSACTIONS_UNSUPPORTED_REMOTE.
The size of the buffer to receive the null-terminated string for the drive and path, in TCHARs.
A pointer to a buffer that receives the null-terminated string for the drive and path.
A pointer to a buffer that receives the address (in lpBuffer) of the final file name component in the path. Specify NULL if you do not need to receive this information.
If lpBuffer points to a directory and not a file, lpFilePart receives 0 (zero).
A handle to the transaction. This handle is returned by the CreateTransaction function.
If the function succeeds, the return value is the length, in TCHARs, of the string copied to lpBuffer, not including the terminating null character.
If the lpBuffer buffer is too small to contain the path, the return value is the size, in TCHARs, of the buffer that is required to hold the path and the terminating null character.
If the function fails for any other reason, the return value is zero. To get extended error information, call GetLastError.
GetFullPathNameTransacted merges the name of the current drive and directory with a specified file name to determine the full path and file name of a specified file. It also calculates the address of the file name portion of the full path and file name. This function does not verify that the resulting path and file name are valid, or that they see an existing file on the associated volume.
Share and volume names are valid input for lpFileName. For example, the following list identities the returned path and file names if test-2 is a remote computer and U: is a network mapped drive:
- If you specify "\\test-2\q$\lh" the path returned is "\\test-2\q$\lh"
- If you specify "\\?\UNC\test-2\q$\lh" the path returned is "\\?\UNC\test-2\q$\lh"
- If you specify "U:" the path returned is "U:\"
If the return value is greater than the value specified in nBufferLength, you can call the function again with a buffer that is large enough to hold the path. For an example of this case as well as using zero length buffer for dynamic allocation, see the Example Code section.
