CURLOPT_USERAGENT(3) curl_easy_setopt options CURLOPT_USERAGENT(3)

CURLOPT_USERAGENT - HTTP user-agent header

#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_USERAGENT, char *ua);

Pass a pointer to a null-terminated string as parameter. It will be used to set the User-Agent: header in the HTTP request sent to the remote server. This can be used to fool servers or scripts. You can also set any custom header with CURLOPT_HTTPHEADER(3).

The application does not have to keep the string around after setting this option.

NULL, no User-Agent: header is used by default.

HTTP, HTTPS

CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
  curl_easy_setopt(curl, CURLOPT_USERAGENT, "Dark Secret Ninja/1.0");
  curl_easy_perform(curl);
}

As long as HTTP is supported

Returns CURLE_OK if HTTP is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
