The FtpCommand function sends commands directly to an FTP server.

Syntax

BOOL FtpCommand(
  __in   HINTERNET hConnect,
  __in   BOOL fExpectResponse,
  __in   DWORD dwFlags,
  __in   LPCTSTR lpszCommand,
  __in   DWORD_PTR dwContext,
  __out  HINTERNET *phFtpCommand
);

Parameters

hConnect [in]

A handle returned from a call to InternetConnect.

fExpectResponse [in]

A Boolean value that indicates whether the application expects a data connection to be established by the FTP server. This must be set to TRUE if a data connection is expected, or FALSE otherwise.

dwFlags [in]

A parameter that can be set to one of the following values.

Value	Meaning
FTP_TRANSFER_TYPE_ASCII	Transfers the file using the FTP ASCII (Type A) transfer method. Control and formatting data is converted to local equivalents.
FTP_TRANSFER_TYPE_BINARY	Transfers the file using the FTP Image (Type I) transfer method. The file is transferred exactly with no changes. This is the default transfer method.

 

lpszCommand [in]

A pointer to a string that contains the command to send to the FTP server.

dwContext [in]

A pointer to a variable that contains an application-defined value used to identify the application context in callback operations.

phFtpCommand [out]

A pointer to a handle that is created if a valid data socket is opened. The fExpectResponse parameter must be set to TRUE for phFtpCommand to be filled.

Return Value

Returns TRUE if successful, or FALSE otherwise. To get a specific error message, call GetLastError.

Remarks

GetLastError can return ERROR_INTERNET_NO_DIRECT_ACCESS if the client application is offline. If one or more of the parameters are invalid, GetLastError will return ERROR_INVALID_PARAMETER.
