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.
