plucky (3) CURLOPT_TFTP_NO_OPTIONS.3.gz

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

       This functionality affects tftp only

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);
         }
       }
