### 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 holding a 12 bit integer). }
           WriteLn (BitSizeOf (d));    { e.g. 16 }
           WriteLn (BitSizeOf (d.x));  { 12 }
           WriteLn (BitSizeOf (d.y))   { 2 }
         end.
