CURLOPT_TFTP_NO_OPTIONS(3) Introduction to Library Functions

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

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);
}
}

AVAILABILITY
