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);
     }
