# CHT_IsPictochatParent

## C Specification

      #include <nitro/cht.h>

      BOOL CHT_IsPictochatParent( const WMBssDesc* pWmBssDesc );

## Arguments

pWmBssDesc | Specifies the pointer to the beacon information being checked.

## Return Values

Returns TRUE if the beacon is determined to be sent by a PictoChat parent. Otherwise, returns FALSE.

## Description

Checks to determine whether the beacon information received by a child during wireless communications is the beacon information of a PictoChat parent. Normally, you should specify parent information that has been obtained with `WM_StartScan`. Because ARM7 directly writes the information obtained by `WM_StartScan`, an inconsistency with the cache may emerge. Thus, before checking the beacon information with this function you should invalidate the cache to which the parent information was written.
