Define Documentation

#define GEOM_CLASS_DEF ( c )

Value:
struct geom_##c##_class geom_##c##_class = { \ .instance_size = sizeof(struct geom_##c), \ .class_name = #c, \ geom_##c##_INIT }

#define GEOM_CLASS_HEAD ( c,

Value:
static inline struct geom_class *geom_##c##_parent(void) { return GEOM_CLASS(p); } \ extern struct geom_##c##_class {geom_##c##_VMT} geom_##c##_class

#define GEOM_CLASS_INIT ( c )

Value:
do { geom_class_count++; GEOM_BASSERT(geom_class_count < GEOM_CLASS_ID_COUNT); \ geom_class_table[geom_class_count] = GEOM_CLASS(c); \ GEOM_CLASS(c)->class_id = geom_class_count; \ GEOM_CLASS(c)->class_parent = geom_##c##_parent(); } while(0)

#define GEOM_INSTANCE_DESTROY2 ( i,
nclass ) do{GEOM_INSTANCE_IS_ASSERT(nclass,i);GLUEE3(geom_,nclass,_destroy)((void *)i);}while(0)

Direct call to destructor and destroy instance.
Can be a little faster than GEOM_INSTANCE_DESTROY.
