The FtpGetFile function transfers the specified file on
the server to the local system.
Parameters
- hClient
- Handle to the client session.
- lpszLocalFile
- A pointer to a null-terminated string that specifies the file
on the local system that will be created, overwritten or appended
to. The file pathing and name conventions must be that of the local
host.
- lpszRemoteFile
- A pointer to a null-terminated string that specifies the file
on the server that will be transferred to the local system. The
file naming conventions must be that of the host operating
system.
- dwOptions
- An unsigned integer that specifies one or more options. This
parameter may be any one of the following values:
| Constant |
Description |
| FTP_TRANSFER_DEFAULT |
This option specifies that the default transfer mode should be
used. If the local file exists, it will be overwritten with the
contents of the downloaded file. |
| FTP_TRANSFER_APPEND |
This option specifies that if the local file exists, the
contents of file on the server is appended to the local file. If
the local file does not exist, it is created. |
- dwOffset
- A byte offset which specifies where the file transfer should
begin. The default value of zero specifies that the file transfer
should start at the beginning of the file. A value greater than
zero is typically used to restart a transfer that has not completed
successfully. Note that specifying a non-zero offset requires that
the server support the REST command to restart transfers.
Return Value
If the function succeeds, the return value is the server result
code. If the function fails, the return value is FTP_ERROR. To get
extended error information, call FtpGetLastError.
Remarks
This function will cause the current thread to block until the
file transfer completes, a timeout occurs or the transfer is
canceled. During the transfer, the FTP_EVENT_PROGRESS event will be
periodically fired, enabling the application to update any user
interface controls. Event notification must be enabled, either by
calling FtpEnableEvents, or by registering a callback
function using the FtpRegisterEvent function.
To determine the current status of a file transfer while it is
in progress, use the FtpGetTransferStatus function.
Requirements
Client: Requires Windows 7, Windows Vista or Windows
XP.
Server: Requires Windows Server 2008 or Windows Server
2003.
Header: Include cstools7.h.
Library: Use csftpav7.lib.
Unicode: Implemented as Unicode and ANSI versions.
