FtpGetFile

BOOL FtpGetFile(
    IN HINTERNET hFtpSession,
    IN LPCSTR lpszRemoteFile,
    IN LPCSTR lpszNewFile,
    IN BOOL fFailIfExists,
    IN DWORD dwLocalFlagsAndAttributes,
    IN DWORD dwInternetFlags,
    IN DWORD dwContext
);

Retrieves a file from the FTP server and stores it under the specified file name, creating a new local file in the process.

hFtpSession
Valid handle to an FTP session.
lpszRemoteFile
Address of a null-terminated string that contains the name of the file to retrieve from the remote system.
lpszNewFile
Address of a null-terminated string that contains the name of the file to create on the local system.
fFailIfExists
Boolean flag that indicates whether the function should proceed if a local file of the specified name already exists. If fFailIfExists is TRUE and the local file exists, FtpGetFile fails.
dwLocalFlagsAndAttributes
File attributes for the new file. Can be any combination of the FILE_ATTRIBUTE_* flags used by the CreateFile function. For more information on FILE_ATTRIBUTE_* attributes, see CreateFile in the Platform SDK.
dwInternetFlags
Flags that control how the function will handle the file download. The first set of flag values indicates the conditions under which the transfer occurs. These transfer type flags can be used in combination with the second set of flags that control caching. The application can select one of these transfer type values:
FTP_TRANSFER_TYPE_ASCII
Transfers the file using FTP's ASCII (Type A) transfer method. Control and formatting information is converted to local equivalents.
FTP_TRANSFER_TYPE_BINARY
Transfers the file using FTP's Image (Type I) transfer method. The file is transferred exactly as it exists with no changes. This is the default transfer method.
FTP_TRANSFER_TYPE_UNKNOWN
Defaults to FTP_TRANSFER_TYPE_BINARY.
INTERNET_FLAG_TRANSFER_ASCII
Transfers the file as ASCII.
INTERNET_FLAG_TRANSFER_BINARY
Transfers the file as binary.
The following flags determine how the caching of this file will be done. Any combination of the following flags can be used with the transfer type flag. The possible values are:
INTERNET_FLAG_DONT_CACHE
Does not add the returned entity to the cache. Identical to the preferred value, INTERNET_FLAG_NO_CACHE_WRITE.
INTERNET_FLAG_HYPERLINK
Forces a reload if there was no Expires time and no Last-Modified time returned from the server when determining whether to reload the item from the network.
INTERNET_FLAG_MAKE_PERSISTENT
No longer supported.
INTERNET_FLAG_MUST_CACHE_REQUEST
Causes a temporary file to be created if the file cannot be cached. Identical to the preferred value, INTERNET_FLAG_NEED_FILE.
INTERNET_FLAG_NEED_FILE
Causes a temporary file to be created if the file cannot be cached.
INTERNET_FLAG_NO_CACHE_WRITE
Does not add the returned entity to the cache.
INTERNET_FLAG_RELOAD
Forces a download of the requested file, object, or directory listing from the origin server, not from the cache.
INTERNET_FLAG_RESYNCHRONIZE
Causes the FTP resource to be reloaded from the server.
dwContext
Application-defined value that associates this search with any application data. This is used only if the application has already called InternetSetStatusCallback to set up a status callback function.

FtpGetFile is a high-level routine that handles all the bookkeeping and overhead associated with reading a file from an FTP server and storing it locally. An application that needs to retrieve file data only or that requires close control over the file transfer should use the FtpOpenFile and InternetReadFile functions.

If the dwTransferType parameter specifies FILE_TRANSFER_TYPE_ASCII, translation of the file data converts control and formatting characters to local equivalents. The default transfer is binary mode, where the file is downloaded in the same format as it is stored on the server.

Both lpszRemoteFile and lpszNewFile can be either partially or fully qualified file names relative to the current directory. A backslash (\) or forward slash (/) can be used as the directory separator for either name. FtpGetFile translates the directory name separators to the appropriate character before they are used.
