$ishalfop(<nick> <channel>)

• If the <nick> argument is omitted, the empty string is returned.
• If the <channel> argument is omitted, or if it is a literal star ('*'), then the current channel is assumed.
• BEWARE – if you are connected to more than one server and the current window is connected to a different server than whatever context this function is called in, it may falsely return 0. To be sure, always specify the channel name!
• This function returns 1 if <nick> is a channel half-operator on <channel>.
• This function uses the internal channel cache:
  • Both you and <nick> must be on <channel> or it will return 0.
  • If /on channel_sync has not been thrown for <channel> it may return 0.

You can use this function to see if someone is a channel half-operator as a condition of some other action.
