NAME

       CURLOPT_TFTP_NO_OPTIONS - send no TFTP options requests

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TFTP_NO_OPTIONS, long onoff);

DESCRIPTION

       Set  onoff  to  1L  to exclude all TFTP options defined in RFC 2347, RFC 2348 and RFC 2349
       from read and write requests.

       This option improves interoperability with legacy  servers  that  do  not  acknowledge  or
       properly  implement  TFTP  options.  When  this  option is used CURLOPT_TFTP_BLKSIZE(3) is
       ignored.

DEFAULT

       0

PROTOCOLS

       TFTP

EXAMPLE

       size_t write_callback(char *ptr, size_t size, size_t nmemb, void *fp)
       {
         return fwrite(ptr, size, nmemb, (FILE *)fp);
       }

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           FILE *fp = fopen("foo.bin", "wb");
           if(fp) {
             curl_easy_setopt(curl, CURLOPT_WRITEDATA, (void *)fp);
             curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_callback);

             curl_easy_setopt(curl, CURLOPT_URL, "tftp://example.com/foo.bin");

             /* do not send TFTP options requests */
             curl_easy_setopt(curl, CURLOPT_TFTP_NO_OPTIONS, 1L);

             /* Perform the request */
             curl_easy_perform(curl);

             fclose(fp);
           }
           curl_easy_cleanup(curl);
         }
       }
