NAME

       CURLOPT_TFTP_NO_OPTIONS - Do not send 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 RFC2347, RFC2348 and RFC2349 from
       read and write requests (RRQs/WRQs).

       This option improves interop with some 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);
       }

       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);
       }

AVAILABILITY
