Return the align of a struct;the default is 1.

Return the endian of a struct;the default is :little.

Return the fields of a struct.

set the options of a struct.

Return the size of a struct;size similar to sizeof in C language.

Example:

  class Point < CStruct
    int32:x
    int32:y
  end

  puts Point.size # or Point.__size__

Define a anonymous struct field.

Example:

in C:

  struct Window
  {
     int style;
     struct{
       int x;
       int y;
     }position;
  };

use CStruct in Ruby:

  class Window < CStruct
    int32:style
    struct :position do
      int32:x
      int32:y
    end
  end

Define a anonymous union field.

Example: in C:

  struct U
  {
     union{
       int x;
       int y;
     }value; /* values is anonymous union's instance */

};

use CStruct in Ruby:

  class U < CStruct
    union:value do
      int32:x
      int32:y
    end
  end
