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

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