BOOL GetFile( LPCTSTRpstrRemoteFile, LPCTSTRpstrLocalFile, BOOLbFailIfExists = TRUE, DWORDdwAttributes
= FILE_ATTRIBUTE_NORMAL, DWORDdwFlags = FTP_TRANSFER_TYPE_BINARY, DWORDdwContext = 1 );
pstrRemoteFile
A pointer to a null-terminated string containing the name of a file to retrieve from the FTP server.
pstrLocalFile
A pointer to a null-terminated string containing the name of the file to create on the local system.
bFailIfExists
Indicates whether the file name may already be used by an existing file. If the local file name already exists, and this parameter isTRUE,GetFile fails. Otherwise,
GetFile will erase the existing copy of the file.
dwAttributes
Indicates the attributes of the file. This can be any combination of the following FILE_ATTRIBUTE_* flags.
- FILE_ATTRIBUTE_ARCHIVE The file is an archive file. Applications use this attribute to mark files for backup or removal.
- FILE_ATTRIBUTE_COMPRESSED The file or directory is compressed. For a file, compression means that all of the data in the file is compressed. For a directory, compression is the default for newly created files and subdirectories.
- FILE_ATTRIBUTE_DIRECTORY The file is a directory.
- FILE_ATTRIBUTE_NORMAL The file has no other attributes set. This attribute is valid only if used alone. All other file attributes override FILE_ATTRIBUTE_NORMAL:
- FILE_ATTRIBUTE_HIDDEN The file is hidden. It is not to be included in an ordinary directory listing.
- FILE_ATTRIBUTE_READONLY The file is read only. Applications can read the file but cannot write to it or delete it.
- FILE_ATTRIBUTE_SYSTEM The file is part of or is used exclusively by the operating system.
- FILE_ATTRIBUTE_TEMPORARY The file is being used for temporary storage. Applications should write to the file only if absolutely necessary. Most of the file’s data remains in memory without being flushed to the media because the file will soon be deleted.
dwFlags
Specifies the conditions under which the transfer occurs. This parameter can be any of thedwFlags values described inFtpGetFile
in thePlatform SDK.
dwContext
The context identifier for the file retrieval. See Remarks for more information aboutdwContext.

BOOL Remove( LPCTSTR pstrFileName );
Return Value
Nonzero if successful; otherwise 0. If the call fails, the Win32 functionGetLastError may be called to determine the cause of the error.

BOOL PutFile( LPCTSTR pstrLocalFile, LPCTSTRpstrRemoteFile, DWORDdwFlags = FTP_TRANSFER_TYPE_BINARY, DWORDdwContext = 1 );
Return Value
Nonzero if successful; otherwise 0. If the call fails, the Win32 functionGetLastError may be called to determine the cause of the error.
Parameters
pstrLocalFile
A pointer to a string containing the name of the file to send from the local system.
pstrRemoteFile
A pointer to a string containing the name of the file to create on the FTP server.
dwFlags
Specifies the conditions under which the transfer of the file occurs. Can be any of the FTP_TRANSFER_* constants described inOpenFile.
dwContext
The context identifier for placing the file. See Remarks for more information aboutdwContext.
