docs/libcurl/opts: clarify the return values

Expand a little.

- mention the type name of the return code
- avoid stating which exact return codes that might be returned, as that
  varies over time, builds and conditions
- avoid stating some always return OK
- refer to the manpage documenting all the return codes

Closes #15900

NAME

CURLOPT_PROXYUSERPWD - username and password to use for proxy authentication

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXYUSERPWD, char *userpwd);

DESCRIPTION

Pass a char pointer as parameter, which should be [username]:[password] to use for the connection to the HTTP proxy. Both the name and the password are URL decoded before used, so to include for example a colon in the username you should encode it as %3A. (This is different to how CURLOPT_USERPWD(3) is used - beware.)

Use CURLOPT_PROXYAUTH(3) to specify the authentication method.

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.

DEFAULT

NULL

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
    curl_easy_setopt(curl, CURLOPT_PROXY, "http://localhost:8080");
    curl_easy_setopt(curl, CURLOPT_PROXYUSERPWD, "clark%20kent:superman");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}

RETURN VALUE

curl_easy_setopt(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
