how to fix error"CURLOPT_USERNAME’ undeclared "in curl ftp programming
 

hi all ,

i have written file transfer program using libcurl.

#include <stdio.h>
#include <curl/curl.h>
#include <curl/types.h>
#include <curl/easy.h>

/*
* This is an example showing how to get a single file from an FTP server.
* It delays the actual destination file creation until the first write
* callback so that it won’t create an empty file in case the remote file
* doesn’t exist or something else fails.
*/
#define UPLOAD_FILE_AS "11.txt"
#define REMOTE_URL "ftp://10.114.5.0/" UPLOAD_FILE_AS

struct FtpFile
{
const char *filename;
FILE *stream;
};

static size_t my_fwrite(void *buffer, size_t size, size_t nmemb, void *stream)
{
struct FtpFile *out=(struct FtpFile *)stream;
if(out && !out->stream)
{
/* open file for writing */
out->stream=fopen(out->filename, "wb");
if(!out->stream)
return -1; /* failure, can’t open file to write */
}
return fwrite(buffer, size, nmemb, out->stream);
}

int main(void)
{
CURL *curl;
CURLcode res;
struct FtpFile ftpfile={"11.txt", NULL}; /* name to store the file as if succesful */
struct curl_slist *headerlist=NULL;
static const char buf_1 [] = "DELE " UPLOAD_FILE_AS;
curl_global_init(CURL_GLOBAL_DEFAULT);

curl = curl_easy_init();

if(curl)
{
/*
* Get curl 7.9.2 from sunet.se’s FTP site. curl 7.9.2 is most likely not
* present there by the time you read this, so you’d better replace the
* URL with one that works!
*/

headerlist = curl_slist_append(headerlist, buf_1);
curl_easy_setopt(curl, CURLOPT_URL, REMOTE_URL);
curl_easy_setopt (curl, CURLOPT_VERBOSE, 1);
curl_easy_setopt (curl, CURLOPT_USERNAME , "v4user");
curl_easy_setopt (curl, CURLOPT_PASSWORD ,"v4user");

/* Define our callback to get called when there’s data to be written */
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, my_fwrite);

/* Set a pointer to our struct to pass to the callback */
curl_easy_setopt(curl, CURLOPT_WRITEDATA, &ftpfile);

/* Switch on full protocol/debug output */
curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L);

curl_easy_setopt(curl, CURLOPT_POSTQUOTE, headerlist);
res = curl_easy_perform(curl);

/* always cleanup */
curl_easy_cleanup(curl);

if(CURLE_OK != res)
{
/* we failed */
fprintf(stderr, "curl told us %d\n", res);
}
}

if(ftpfile.stream)
fclose(ftpfile.stream); /* close the local file */

curl_global_cleanup();

return 0;

}


i am using command for compile:--
"gcc ftpget.c -o ftpget.o -lcurl"


on this command i getting these error:

ftpget.c:53: error: ‘CURLOPT_USERNAME’ undeclared (first use in this function)
ftpget.c:53: error: (Each undeclared identifier is reported only once
ftpget.c:53: error: for each function it appears in.)
ftpget.c:54: error: ‘CURLOPT_PASSWORD’ undeclared (first use in this function)

plz help me how to remove above error......is it required any more header file to include?

Have you tried asking this in the programming forum? This looks a bit beyond Newbie to me!
