CURLOPT_PROXY_SERVICE_NAME - Man Page

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SERVICE_NAME,
                          char *name);

Pass a char pointer as parameter to a string holding the name of the service. The default service name is "HTTP" for HTTP based proxies and "rcmd" for SOCKS5. This option allows you to change it.

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

Using this option multiple times makes the last set string override the previous ones. Set it to NULL to disable its use again.

See above

This functionality affects all supported protocols

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode ret;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
    curl_easy_setopt(curl, CURLOPT_PROXY_SERVICE_NAME, "custom");
    ret = curl_easy_perform(curl);
  }
}

Added in curl 7.43.0

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