LInetFtp::LInetFtp

#include "ltwrappr.h"

L_VOID LInetFtp::LInetFtp(L_VOID)

L_VOID LInetFtp::LInetFtp(pszServer, pszUserName = NULL, pszPassword = NULL, nPort = 21)

L_TCHAR *pszServer;	/* name of server to connect to */
L_TCHAR *pszUserName;	/* username for authentication */
L_TCHAR *pszPassword;	/* password for authentication */
L_INT nPort;	/* port number to connect to */

Constructs and initializes the member variables of the LInetFtp object.

Parameter	Description
pszServer	Character string that contains the host name of an FTP server. This can be a URL, like ftp.leadtools.com, or it can contain the IP number of the site, in ASCII dotted-decimal format (for example, 208.35.195.11).
pszUserName	Character string that contains the name of the user logging on. Default value is NULL. This is a NULL-terminated string.
pszPassword	Character string that contains the password to use when logging on. Default value is NULL. This is a NULL-terminated string.
nPort	Number of the TCP/IP port on the server to connect to. These flags set only the port that will be used. Use the default port for FTP servers: INTERNET_DEFAULT_FTP_PORT (port 21).

Returns

None

Comments

LInetFtp::LInetFtp() is the default LInetFtp constructor. After calling the this constructor, a user must call LInetFtp::Connect to establish a connection before using other functions.

LInetFtp::LInetFtp(pszServer, pszUserName = NULL, pszPassword = NULL, nPort = 21) is a constructor for the LInetFtp object. It connects to the FTP server. If both pszUserName and pszPassword are NULL, the connection is made anonymously.

A connection to an FTP server must be established before using any other FTP functions. If a connection is disconnected, via either LInetFtp::Disconnect or LInetFtp::~LInetFtp, then a connection must be re-established before any other FTP functions are called. LInetFtp::Connect and LInetFtp::LInetFtp can be used to establish a connection with an FTP server.
