## Description

Checks the PictoChat parent's beacon information to determine the number of members (`1` to `16`) participating in the room opened by the PictoChat parent. Before using this function to get the number of members, be sure to use `CHT_IsPictochatParent()` to make sure that the beacon information being checked is that of a PictoChat parent. If it is not the beacon information of a PictoChat parent, an undefined value will be returned to the argument.
