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_PASSWORD - password to use in authentication

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PASSWORD, char *pwd);

DESCRIPTION

Pass a char pointer as parameter, which should be pointing to the null-terminated password to use for the transfer.

The CURLOPT_PASSWORD(3) option should be used in conjunction with the CURLOPT_USERNAME(3) option.

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

blank

EXAMPLE

{
  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_PASSWORD, "qwerty");

    res = curl_easy_perform(curl);

    curl_easy_cleanup(curl);
  }
}
