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_NETRC_FILE - filename to read .netrc info from

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_NETRC_FILE, char *file);

DESCRIPTION

Pass a char pointer as parameter, pointing to a null-terminated string containing the full path name to the file you want libcurl to use as .netrc file. If this option is omitted, and CURLOPT_NETRC(3) is set, libcurl checks for a .netrc file in the current user's home directory.

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 ret;
    curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com/");
    curl_easy_setopt(curl, CURLOPT_NETRC, CURL_NETRC_OPTIONAL);
    curl_easy_setopt(curl, CURLOPT_NETRC_FILE, "/tmp/magic-netrc");
    ret = curl_easy_perform(curl);
  }
}

%AVAILABILITY%

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).
