-Let's print GUID for all the protocols that are exist in our `IMAGE_HANDLE`.
-
-First understand what `EFI_GUID` internally means in the edk2 codebase:
-
-https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Uefi/UefiBaseType.h
-```
-///
-/// 128-bit buffer containing a unique identifier value.
-///
-typedef GUID                      EFI_GUID;
-```
-`GUID` structure is defined in https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Base.h :
-```
-///
-/// 128 bit buffer containing a unique identifier value.
-/// Unless otherwise specified, aligned on a 64 bit boundary.
-///
-typedef struct {
-  UINT32  Data1;
-  UINT16  Data2;
-  UINT16  Data3;
-  UINT8   Data4[8];
-} GUID;
-```
-Fortunately we don't have to manually print all these fields by hand. `Print` function has a format option `%g` to print GUIDs, so we could simply print GUIDs with a code like this:
-```
-Print("GUID=%g\n", myGUID);
-```
-More information about `Print` formating options can be found at https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Library/PrintLib.h
-
-
-We want to print `EFI_GUID` field from the `PROTOCOL_ENTRY` structure which are referred from the `PROTOCOL_INTERFACE` structures. So we need to define both of these structures in our file for the same reason we've defined `IHANDLE` earlier.
-
-```
-typedef struct {
-  UINTN               Signature;
-  /// Link Entry inserted to mProtocolDatabase
-  LIST_ENTRY          AllEntries;
-  /// ID of the protocol
-  EFI_GUID            ProtocolID;
-  /// All protocol interfaces
-  LIST_ENTRY          Protocols;
-  /// Registerd notification handlers
-  LIST_ENTRY          Notify;
-} PROTOCOL_ENTRY;
-
-typedef struct {
-  UINTN                       Signature;
-  /// Link on IHANDLE.Protocols
-  LIST_ENTRY                  Link;
-  /// Back pointer
-  IHANDLE                     *Handle;
-  /// Link on PROTOCOL_ENTRY.Protocols
-  LIST_ENTRY                  ByProtocol;
-  /// The protocol ID
-  PROTOCOL_ENTRY              *Protocol;
-  /// The interface value
-  VOID                        *Interface;
-  /// OPEN_PROTOCOL_DATA list
-  LIST_ENTRY                  OpenList;
-  UINTN                       OpenListCount;
-
-} PROTOCOL_INTERFACE;
-```
-
-`PROTOCOL_INTERFACE` structures that are connected to any HANDLE are interlinked with each other with a help of a `LIST_ENTRY Link` field that connects them to a double linked list.
-
-As you may remember `LIST_ENTRY` is defined like this:
-```
-///
-/// LIST_ENTRY structure definition.
-///
-typedef struct _LIST_ENTRY LIST_ENTRY;
-
-///
-/// _LIST_ENTRY structure definition.
-///
-struct _LIST_ENTRY {
-  LIST_ENTRY  *ForwardLink;
-  LIST_ENTRY  *BackLink;
-};
-```
-Each of these fields inside these structure points to another `LIST_ENTRY` structure that is placed in another `PROTOCOL_INTERFACE`.
-
-So this connection looks like this:
-
-```
-typedef struct {                                         typedef struct {
-  UINTN                       Signature;                   UINTN                       Signature;
-  struct LIST_ENTRY {                          |---------> struct LIST_ENTRY {
-    LIST_ENTRY  *ForwardLink; -----------------|             LIST_ENTRY  *ForwardLink;
-    LIST_ENTRY  *BackLink;                                   LIST_ENTRY  *BackLink;
-  } Link;                                                  } Link;
-  IHANDLE                     *Handle;                     IHANDLE                     *Handle;
-  LIST_ENTRY                  ByProtocol;                  LIST_ENTRY                  ByProtocol;
-  PROTOCOL_ENTRY              *Protocol;                   PROTOCOL_ENTRY              *Protocol;
-  VOID                        *Interface;                  VOID                        *Interface;
-  LIST_ENTRY                  OpenList;                    LIST_ENTRY                  OpenList;
-  UINTN                       OpenListCount;               UINTN                       OpenListCount;
-} PROTOCOL_INTERFACE;                                    } PROTOCOL_INTERFACE;
-```
-
-But in reality we want a pointer not to `Link` field of another `PROTOCOL_INTERFACE` structure, we want a pointer to another `PROTCOL_INTERFACE` structure inself.
-
-Therefore one more thing that we would need is a couple of macros:
-```
-#define offsetof(a,b) ((INTN)(&(((a*)(0))->b)))
-
-#define container_of(ptr, type, member) ({                      \
-        const typeof( ((type *)0)->member ) *__mptr = (ptr);    \
-        (type *)( (char *)__mptr - offsetof(type,member) );})
-```
-These macros can be familiar to you if you've investigated linux kernel programming. This is where I got them from anyway.
-
-`contianer_of` macro helps to get a pointer to a structure if you have a pointer to one of its fields.
-
-If you want to understand how it works internally in C language I suggest you to look at the https://stackoverflow.com/questions/15832301/understanding-container-of-macro-in-the-linux-kernel
-
-With all of this information final code for our `UefiMain` function would look like this:
-```
-EFI_STATUS
-EFIAPI
-UefiMain (
-  IN EFI_HANDLE        ImageHandle,
-  IN EFI_SYSTEM_TABLE  *SystemTable
-  )
-{
-  IHANDLE* MyHandle = ImageHandle;
-  Print(L"Signature: %c %c %c %c\n", (MyHandle->Signature >>  0) & 0xff,
-                                     (MyHandle->Signature >>  8) & 0xff,
-                                     (MyHandle->Signature >> 16) & 0xff,
-                                     (MyHandle->Signature >> 24) & 0xff);
-
-  Print(L"Back Protocol Interface Link: %p\n", MyHandle->Protocols.BackLink);
-  Print(L"Forward Protocol Interface Link: %p\n", MyHandle->Protocols.ForwardLink);
-
-  LIST_ENTRY *FirstLink = MyHandle->Protocols.ForwardLink;
-  LIST_ENTRY *CurrentLink = FirstLink;
-  do {
-        PROTOCOL_INTERFACE* MyProtocolInterface = container_of(CurrentLink, PROTOCOL_INTERFACE, Link);
-
-        Print(L"\n");
-        Print(L"Current Link: %p\n", CurrentLink);
-        Print(L"Signature: %c %c %c %c\n", (MyProtocolInterface->Signature >>  0) & 0xff,
-                                           (MyProtocolInterface->Signature >>  8) & 0xff,
-                                           (MyProtocolInterface->Signature >> 16) & 0xff,
-                                           (MyProtocolInterface->Signature >> 24) & 0xff);
-
-        Print(L"Back Link: %p\n", MyProtocolInterface->Link.BackLink);
-        Print(L"Forward Link: %p\n", MyProtocolInterface->Link.ForwardLink);
-        Print(L"GUID=%g\n", MyProtocolInterface->Protocol->ProtocolID);
-        CurrentLink = MyProtocolInterface->Link.ForwardLink;
-  } while (CurrentLink != FirstLink);
-
-  return EFI_SUCCESS;
-}
-```
-
-If we compile and run our app in OVMF (I hope at this time I don't need to repeat how to do it):
-```

-GUID=00000000-0000-0000-0000-000000000000
-```
-
-Let's find first GUID by executing grep on the edk2 source:
-```
-$ grep -i 752F3136 -r ./ --exclude-dir=Build
-./MdePkg/Include/Protocol/ShellParameters.h:  0x752f3136, 0x4e16, 0x4fdc, { 0xa2, 0x2a, 0xe5, 0xf4, 0x68, 0x12, 0xf4, 0xca } \
-./MdePkg/MdePkg.dec:  gEfiShellParametersProtocolGuid      = { 0x752f3136, 0x4e16, 0x4fdc, {0xa2, 0x2a, 0xe5, 0xf4, 0x68, 0x12, 0xf4, 0xca }}
-```
-
-https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Protocol/ShellParameters.h
-```
-#define EFI_SHELL_PARAMETERS_PROTOCOL_GUID \
-  { \
-  0x752f3136, 0x4e16, 0x4fdc, { 0xa2, 0x2a, 0xe5, 0xf4, 0x68, 0x12, 0xf4, 0xca } \
-  }
-```
-You can also see in in a https://github.com/tianocore/edk2/blob/master/MdePkg/MdePkg.dec file:
-```
-  ## Include/Protocol/ShellParameters.h
-  gEfiShellParametersProtocolGuid      = { 0x752f3136, 0x4e16, 0x4fdc, {0xa2, 0x2a, 0xe5, 0xf4, 0x68, 0x12, 0xf4, 0xca }}
-```
-
-The next two GUIDs you can find in UEFI the specification.
-
-`EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL` - When installed, the Loaded Image Device Path Protocol specifies the device path that was used when a PE/COFF image was loaded through the EFI Boot Service LoadImage().
-
-```
-#define EFI_LOADED_IMAGE_DEVICE_PATH_PROTOCOL_GUID \
-{0xbc62157e,0x3e33,0x4fec,\
- {0x99,0x20,0x2d,0x3b,0x36,0xd7,0x50,0xdf}}
-```
-
-`EFI_LOADED_IMAGE_PROTOCOL` - Can be used on any image handle to obtain information about the loaded image.
-```
-#define EFI_LOADED_IMAGE_PROTOCOL_GUID\
- {0x5B1B31A1,0x9562,0x11d2,\
- {0x8E,0x3F,0x00,0xA0,0xC9,0x69,0x72,0x3B}}
-```
-
-The last `PROTOCOL_INTERFACE` structure doesn't have a valid "p i f c" signature (in my case it is 0x20 0x0E 0xED 0x06), so we don't need to look at its GUID.
