    checking x size of multi 2-d array

    I am passing a multi-2d array through a routine, and this routine is used several times with different x sized 2-d arrays.
    NOTE: The y coordinate is always 15.

    Is there a way to extract the size of the x coordinate of the passed array?

    For example, can you get the size of x in scan_list[x][15], as shown below within the routine?

    Code:
    byte check_for_duplicate_codes( byte *scan, byte scan_list[][15] )
    {
    
     ...
    
     // I want to use the size of x in scan_list[x][15] in here.
    
    }

    No you'll need to pass it as another parameter
