  // CURL_GLOBAL_ALL combines all initialization flags.
  CURL_GLOBAL_ALL: i64 = 3

It has nothing to do with "curl_global_init()". This - which is a high-level function intended to be called by the users of the library - has:

  init :: proc() -> (ok: bool) {
    return curl_global_init(CURL_GLOBAL_ALL) == 0
  }

As you can see, higher-level function calls low-level function. The higher-level function does not have "curl" as the prefix.

My question still stands and has not been answered.
