i just wrote a program to just read a file as the file will store all the necessary inputs for login like IP,User,Pass.
and stored in structure but dont know to which should i pass these arguments for login.i already have created an FTP server by installing "VSFTPD package"..can u assist on this.

can you show the code you have written?

its just reading program from the file nothing much..
structure wise
#include /*Header files*/
typedef struct
{
char ip;
char user;
char pass;

}info;

main()
{
FILE *fp;/*file to read details*/
info *data=NULL;
a=data->ip;
b=data->user;
c=data->pass;
/*Required method to pass these arguments*/

methodLogin(a,b,c);/*At this point i need assistance for my semester project as i thought to do*/

return 0;
}

yes, you need to open file and parse data. here is a little example on how to open and read a file using fopen and fscanf. Can you fill up the ip, user and pass variables?

i did writing & modification for the parse program as here..
so what further in case the login to FTP commented below!!


#include <stdio.h>
//#include <io.h>
#include <stdlib.h>
#include<string.h>
typedef struct
{
char ip[16];
char user[16];
char pass[16];
}info;


int main(void)
{
FILE *fp;
/*
char ip[16];
char user[16];
char pass[16];
int t;
*/
info *value=NULL;
value=(info *)malloc(sizeof(info));
memset(value,0,sizeof(info));
if((fp=fopen("test", "w")) == NULL) {
printf("Cannot open file.\n");
exit(1);
}

printf("Enter IP,USER,PASS: ");
fscanf(stdin, "%s %s %s",value->ip,value->user,value->pass); /* read from keyboard */

fprintf(fp, "%s %s %s", value->ip,value->user,value->pass); /* write to file */
fclose(fp);

if((fp=fopen("test","r")) == NULL) {
printf("Cannot open file.\n");
exit(1);
}

fscanf(fp, "%s %s %s", value->ip,value->user,value->pass); /* read from file */
fprintf(stdout, "IP:%s\nUSER:%s\nPASS:%s\n\n", value->ip,value->user,value->pass); /* print on screen */


/*FTP LOGIN*/
FtpLogin(value->ip,value->user,value->pass);

return 0;
}

There are some problems with your code, but first: please use [code][/code] to keep formatting your code.

1. probably 16 bytes are not enough to store ip/user/pass. In case of overflow your app may die with a segmentation fault or similar, or will destroy some data inside.
2. you did not check the result of fscanf.
3. here is a simple ftp client: http://enggedu.com/lab_exercise/netw...FTP_client.php. With this you can connect to a server.
4. you can try to log in, send commands and receive response.

here is an api, but you need to compile it. I assume it will not cause any problem.
Also a collection: http://curl.haxx.se/libcurl/competitors.html. Libcurl has a few example also: http://curl.haxx.se/libcurl/c/ftpupload.html

Thanx vry much!
i m going through all the APIs n got stuck in one argument.i m giving u the url of function and argument i stuck with.

function URL:
http://nbpfaus.net/~pfau/ftplib/FtpConnect.html

Problem:
int FtpConnect(const char *host, netbuf **nControl);
what to pass here for "netbuf **nControl"
--

that is written on the page: nControl is the return value, you will get a handle which can be used to initiate data transfers.

i got that point.

but if i call like this,giving only one argument,it gives error like
so wat structure ref should i pass there..
will u please write that function with its passing arguments.with that argument declaration.
coz for last 2hrs i am searching for "Arguments for FtpConnect" in google and result is ZERO
--

that is written, you do not understand: you must give a second argument, which is a pointer:

just perfectly fine and running successfully..
jst got stuck in sending & receiving files..Actually program halts at some point after entering to the function FtpGet(...)
Putting Rough structure in here,have a look on FtpGet() function plz
giving you details..
