Example of Channel Polymorphism MemoryChannel to Linkable or BaseChannel
ALL Channel Types can be cast as a "BaseChannel"
First element of a core or sub channel is always a Channel struct.
First element of Channel Struct is a Stuct Linkable.

struct Channel          //@struct Channel
{
struct Linkable node;           //-- struct Linkable tLink =(struct Linkable *)Channel. Now its Linkable.
struct Channel *parent_channel; //
uint64_t io_flagbits;           //read. 0xffff0000 0x0000ffff write
uint64_t ch_index;  
char name     [256];
char code_base[256];
char url      [256];
char  *read_buffer;  //
char  *write_buffer; //
volatile char    *io_ctl[4];       // read(0 system 1 user).write(2 system,3 user)
volatile char    *read_list[16][2];
volatile char    *write_list[16][2];
struct StateMachine *state_machine;
struct GraphicsContext graphics;
struct Runtime         *runtime;
struct Channel         *sub_channel[16];
};
