EXAMPLE
static size_t read_cb(char *ptr, size_t size, size_t nmemb, void *userdata)
{
FILE *src = userdata;
/* copy as much data as possible into the 'ptr' buffer, but no more than
'size' * 'nmemb' bytes */
size_t retcode = fread(ptr, size, nmemb, src);
return retcode;
}
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
FILE *src = fopen("local-file", "r");
curl_off_t fsize = 123456; /* set this to the size of the input file */
/* we want to use our own read function */
curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_cb);
/* enable PUT */
curl_easy_setopt(curl, CURLOPT_PUT, 1L);
/* specify target */
curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/dir/to/newfile");
/* now specify which pointer to pass to our callback */
curl_easy_setopt(curl, CURLOPT_READDATA, src);
/* Set the size of the file to upload */
curl_easy_setopt(curl, CURLOPT_INFILESIZE_LARGE, (curl_off_t)fsize);
