Classes
struct	struct_field
	structure to store field list of parsed structs. A struct may have multiple field, and each field may be an array, or a struct. We use a single linked list to store the fields of a struct. More...

struct	struct_container
	structure to store parsed structs. A struct may have multiple fields, we put fields in a linked list. More...

struct	pos
	position of string More...
