struct (make structures, enums, data types from symbols)

Command
struct
Syntax
struct [Module!SymbolName (string)] [padding Padding (yesno)] [offset Offset (yesno)] [bitfield Bitfield (yesno)] [native Native (yesno)] [decl Declaration (yesno)] [def Definitions (yesno)] [func Functions (yesno)] [pragma Pragma (yesno)] [prefix Prefix (string)] [suffix Suffix (string)] [inline Expantion (string)] [output FileName (string)]
Description
Displays structures, enums, and data types in a C (header) format.
You can use this command to create C (header) files from all of the symbols (structures, enums, data types) in the modules by using module!*. See examples for more information.
Parameters
[Module!SymbolName (string)]
Module name combined with the symbol name (separated by a ! sign).
[padding Padding (yesno)] (optional)
Create padding members. (default: yes)
[offset Offset (yesno)] (optional)
Show offsets. (default: yes)
[bitfield Bitfield (yesno)] (optional)
Allow bitfields in the union. (default: no)
[native Native (yesno)] (optional)
Use types from stdint.h instead of native types. (default: no)
[decl Declaration (yesno)] (optional)
Print declarations. (default: yes)
[def Definitions (yesno)] (optional)
Print definitions. (default: yes)
[func Functions (yesno)] (optional)
Print functions. (default: no)
[pragma Pragma (yesno)] (optional)
Print #pragma pack directives. (default: yes)
[prefix Prefix (string)] (optional)
Prefix for all symbols.
[suffix Suffix (string)] (optional)
Suffix for all symbols.
[inline Expantion (string)] (optional)
Specifies expansion of nested structures/unions. (default: unnamed)
   none: only the top-most type is printed.
   unnamed: unnamed types are nested.
   all: all types are nested.
[output FileName (string)] (optional)
Specifies the output file if the user wants to save the printed data.

You can aslo use this command to rebuild enums.
HyperDbg> struct nt!POWER_ACTION
enum POWER_ACTION
{
  PowerActionNone = 0,
  PowerActionReserved = 1,
  PowerActionSleep = 2,
  PowerActionHibernate = 3,
  PowerActionShutdown = 4,
  PowerActionShutdownReset = 5,

};
It's possible to dump all of the structures, enums, and data types into a header file.
1: kHyperDbg> struct nt!* output NtHeader.h
The following command is used to inline each structure into the parent structure.
HyperDbg> struct nt!_SID inline all
typedef struct _SID

IOCTL
None
Remarks
For implementing this command, pdbex is integrated into HyperDbg.
This command is guaranteed to keep debuggee in a halt state (in Debugger Mode); thus, nothing will change during its execution.
Requirements
None
