CURLOPT_TFTP_NO_OPTIONS(3) curl_easy_setopt options CURLOPT_TFTP_NO_OPTIONS(3)

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
       Added in 7.48.0

RETURN VALUE
       Returns	CURLE_OK  if the option is supported, and CURLE_UNKNOWN_OPTION
       if not.
