CURLOPT_TFTP_NO_OPTIONS - Do not send TFTP options requests. #include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TFTP_NO_OPTIONS, long onoff); 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. 0 TFTP

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);

Added in 7.48.0 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
