typedef struct { GB_CLASS klass; intptr_t ref; } GB_BASE;

This structure represents the base of every Gambas object. It must be placed in the beginning of all object structure defined in a component.

  • The klass field is the class of the object.

  • The ref field is its reference counter.

Do not touch them ! They are managed by the interpreter.
