    <p>I have been unsuccessful in uploading a file onto a FTP server with "curl_easy_perform() failed: failed FTP upload (the STOR command) " as an error.i googled a lot but can't find any solution or suggestion. here is my tiny code</p> <pre><code>#define LOCAL_FILE "D:/er.txt" #define REMOTE_URL "ftp://ftp.nso.edu/incoming/" using namespace std; static size_t read_callback(void *ptr, size_t size, size_t nmemb, void *stream) { curl_off_t nread; size_t retcode = fread(ptr, size, nmemb, (FILE*)stream); nread = (curl_off_t)retcode; fprintf(stderr, "*** We read %" CURL_FORMAT_CURL_OFF_T " bytes from file\n", nread); return retcode; } int main() { CURL *curl; CURLcode res; FILE *hd_src; struct stat file_info; curl_off_t fsize; struct curl_slist *headerlist=NULL; /* get the file size of the local file */ if(stat(LOCAL_FILE, &amp;file_info)) { printf("Couldnt open '%s': %s\n", LOCAL_FILE, strerror(errno)); return 1; } fsize = (curl_off_t)file_info.st_size; printf("Local file size: %" CURL_FORMAT_CURL_OFF_T " bytes.\n", fsize); /* get a FILE * of the same file */ hd_src = fopen(LOCAL_FILE, "rb"); /* In windows, this will init the winsock stuff */ curl_global_init(CURL_GLOBAL_ALL); /* get a curl handle */ curl = curl_easy_init(); if(curl) { /* we want to use our own read function */ curl_easy_setopt(curl, CURLOPT_READFUNCTION, read_callback); /* enable uploading */ curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L); /* specify target */ curl_easy_setopt(curl,CURLOPT_URL, REMOTE_URL); /* pass in that last of FTP commands to run after the transfer */ curl_easy_setopt(curl, CURLOPT_POSTQUOTE, headerlist); /* now specify which file to upload */ curl_easy_setopt(curl, CURLOPT_READDATA, hd_src); /* Set the size of the file to upload (optional).
