The ftpclient package provides an FTP (File Transfer Protocol) client

for use with the TCP/IP stack in eCos. It supports both IPv4 and IPv6

and will use the DNS client, when its is part of the eCos configuration.

This package implements an FTP client.  The API is in include file

install/include/ftpclient.h and it can be used thus:

#include <network.h>

#include <ftpclient.h>

It looks like this:

int ftp_get(char * hostname,

            char * username,

            char * passwd,

            char * filename,

            char * buf,

            unsigned buf_size,

            ftp_printf_t ftp_printf);

Use the FTP protocol to retrieve a file from a server. Only binary

mode is supported. The filename can include a directory name. Only

use unix style ‘/’ file separators,

not ‘\’.

The file is placed into buf.

buf has maximum size buf_size.

If the file is bigger than this, the

transfer fails and FTP_TOOBIG is returned.

Other error codes listed in the header can also be returned.

If the transfer is successful the number of bytes received is returned.

int ftp_put(char * hostname,

            char * username,

            char * passwd,

            char * filename,

            char * buf,

            unsigned buf_size,

            ftp_printf_t ftp_printf);

Use the FTP protocol to send a file to a server.

Only binary

mode is supported. The filename can include a directory name. Only

use unix style ‘/’ file separators,

not ‘\’.

The contents of buf are placed into the file on the

server. If an error occurs one of the codes listed will be returned. If the

transfer is successful zero is returned.

void ftpclient_printf(unsigned error, const char *fmt, ...);

ftp_get() and ftp_put

take a pointer to a function to use for printing

out diagnostic and error messages. This is a sample implementation

which can be used if you don't want to implement the function

yourself.

error will be true when the message to print is an

error message. Otherwise the message is diagnostic, eg. the commands sent

and received from the server.
