### BitSizeOf

#### Synopsis

    function BitSizeOf (var x): SizeType;

#### Description

Returns the size of a type or variable in bits.

#### Conforming to

`BitSizeOf` is a GNU Pascal extension.

#### Example

    program BitSizeOfDemo;
    type
      Int12 = Integer attribute (Size = 12);
    var
      a: Integer;
      b: array [1 .. 8] of Char;
      c: Int12;
      d: packed record
           x: Int12;
           y: 0 .. 3
         end;
    begin
      WriteLn (BitSizeOf (a));    { Size of an `Integer'; usually 32 bits. }
      WriteLn (BitSizeOf (Integer));  { The same. }
      WriteLn (BitSizeOf (b));    { Size of eight `Char's; usually 64 bits. }
      WriteLn (BitSizeOf (c));    { e.g. 16 bits (smallest addressable space). }
      WriteLn (BitSizeOf (d));    { e.g. 16 }
      WriteLn (BitSizeOf (d.x));  { 12 }
      WriteLn (BitSizeOf (d.y))   { 2 }
    end.
