#define INVALID_SOCKET;
macro used to provide portability of code to windows sockets the value to be used when the socket is not valid
void ftpDataCallback (void * userData,
const char * data,
int len)
A callback for the xmlNanoFTPGet command.
| userData: | the user provided context |
| data: | the data received |
| len: | its size in bytes |
void ftpListCallback (void * userData,
const char * filename,
const char * attrib,
const char * owner,
const char * group,
unsigned long size,
int links,
int year,
const char * month,
int day,
int hour,
int minute)
A callback for the xmlNanoFTPList command. Note that only one of year and day:minute are specified.
| userData: | user provided data for the callback |
| filename: | the file name (including "->" when links are shown) |
| attrib: | the attribute string |
| owner: | the owner string |
| group: | the group string |
| size: | the file size |
| links: | the link count |
| year: | the year |
| month: | the month |
| day: | the day |
| hour: | the hour |
| minute: | the minute |
int xmlNanoFTPCheckResponse (void * ctx)
Check if there is a response from the FTP server after a command.
| ctx: | an FTP context |
| Returns: | the code number, or 0 |
void xmlNanoFTPCleanup (void)
Cleanup the FTP protocol layer. This cleanup proxy information.
int xmlNanoFTPClose (void * ctx)
Close the connection and both control and transport
| ctx: | an FTP context |
| Returns: | -1 in case of error, 0 otherwise |
int xmlNanoFTPCloseConnection (void * ctx)
Close the data connection from the server
| ctx: | an FTP context |
| Returns: | -1 in case of error, 0 otherwise |
int xmlNanoFTPConnect (void * ctx)
Tries to open a control connection
| ctx: | an FTP context |
| Returns: | -1 in case of error, 0 otherwise |
void * xmlNanoFTPConnectTo (const char * server,
int port)
Tries to open a control connection to the given server/port
| server: | an FTP server name |
| port: | the port (use 21 if 0) |
| Returns: | an fTP context or NULL if it failed |
int xmlNanoFTPCwd (void * ctx,
const char * directory)
Tries to change the remote directory
| ctx: | an FTP context |
| directory: | a directory on the server |
| Returns: | -1 in case of error, 1 if CWD worked, 0 if it failed |
int xmlNanoFTPDele (void * ctx,
const char * file)
Tries to delete an item (file or directory) from server
| ctx: | an FTP context |
| file: | a file or directory on the server |
| Returns: | -1 in case of error, 1 if DELE worked, 0 if it failed |
void xmlNanoFTPFreeCtxt (void * ctx)
Frees the context after closing the connection.
| ctx: | an FTP context |
int xmlNanoFTPGet (void * ctx,
ftpDataCallback callback,
void * userData,
const char * filename)
Fetch the given file from the server. All data are passed back in the callbacks. The last callback has a size of 0 block.
| ctx: | an FTP context |
| callback: | the user callback |
| userData: | the user callback data |
| filename: | the file to retrieve |
| Returns: | -1 in case of error, 0 otherwise |
SOCKET xmlNanoFTPGetConnection (void * ctx)
Try to open a data connection to the server. Currently only passive mode is supported.
| ctx: | an FTP context |
| Returns: | -1 in case of error, 0 otherwise |
int xmlNanoFTPGetResponse (void * ctx)
Get the response from the FTP server after a command.
| ctx: | an FTP context |
| Returns: | the code number |
SOCKET xmlNanoFTPGetSocket (void * ctx,
const char * filename)
Initiate fetch of the given file from the server.
| ctx: | an FTP context |
| filename: | the file to retrieve (or NULL if path is in context). |
| Returns: | the socket for the data connection, or <0 in case of error |
void xmlNanoFTPInit (void)
Initialize the FTP protocol layer. Currently it just checks for proxy information, and get the hostname
int xmlNanoFTPList (void * ctx,
ftpListCallback callback,
void * userData,
const char * filename)
Do a listing on the server. All files info are passed back in the callbacks.
| ctx: | an FTP context |
| callback: | the user callback |
| userData: | the user callback data |
| filename: | optional files to list |
| Returns: | -1 in case of error, 0 otherwise |
void * xmlNanoFTPNewCtxt (const char * URL)
Allocate and initialize a new FTP context.
| URL: | The URL used to initialize the context |
| Returns: | an FTP context or NULL in case of error. |
void * xmlNanoFTPOpen (const char * URL)
Start to fetch the given ftp:// resource
| URL: | the URL to the resource |
| Returns: | an FTP context, or NULL |
void xmlNanoFTPProxy (const char * host,
int port,
const char * user,
const char * passwd,
int type)
Setup the FTP proxy information. This can also be done by using ftp_proxy ftp_proxy_user and ftp_proxy_password environment variables.
| host: | the proxy host name |
| port: | the proxy port |
| user: | the proxy user name |
| passwd: | the proxy password |
| type: | the type of proxy 1 for using SITE, 2 for USER a@b |
int xmlNanoFTPQuit (void * ctx)
Send a QUIT command to the server
| ctx: | an FTP context |
| Returns: | -1 in case of error, 0 otherwise |
int xmlNanoFTPRead (void * ctx,
void * dest,
int len)
This function tries to read @len bytes from the existing FTP connection and saves them in @dest. This is a blocking call.
| ctx: | the FTP context |
| dest: | a buffer |
| len: | the buffer length |
| Returns: | the number of byte read. 0 is an indication of an end of connection. -1 indicates a parameter error. |
void xmlNanoFTPScanProxy (const char * URL)
(Re)Initialize the FTP Proxy context by parsing the URL and finding the protocol host port it indicates. Should be like ftp://myproxy/ or ftp://myproxy:3128/ A NULL URL cleans up proxy information.
| URL: | The proxy URL used to initialize the proxy context |
int xmlNanoFTPUpdateURL (void * ctx,
const char * URL)
Update an FTP context by parsing the URL and finding new path it indicates. If there is an error in the protocol, hostname, port or other information, the error is raised. It indicates a new connection has to be established.
| ctx: | an FTP context |
| URL: | The URL used to update the context |
| Returns: | 0 if Ok, -1 in case of error (other host). |
