IMAGEHLP_SYMBOLW64 structure (dbghelp.h)

Contains symbol information.

Syntax

typedef struct _IMAGEHLP_SYMBOLW64 {
  DWORD   SizeOfStruct;
  DWORD64 Address;
  DWORD   Size;
  DWORD   Flags;
  DWORD   MaxNameLength;
  WCHAR   Name[1];
} IMAGEHLP_SYMBOLW64, *PIMAGEHLP_SYMBOLW64;

Members

SizeOfStruct

The size of the structure, in bytes. The caller must set this member to sizeof(IMAGEHLP_SYMBOL64).

Address

The virtual address for the symbol.

Size

The size of the symbol, in bytes. This value is a best guess and can be zero.

Flags

This member is reserved for use by the operating system.

MaxNameLength

The maximum length of the string that the Name member can contain, in characters, not including the null-terminating character. Because symbol names can vary in length, this data structure is allocated by the caller. This member is used so the library knows how much memory is available for use by the symbol name.

Name[1]

The decorated or undecorated symbol name. If the buffer is not large enough for the complete name, it is truncated to MaxNameLength characters, including the null-terminating character.

Remarks

This structure supersedes the IMAGEHLP_SYMBOL structure. For more information, see Updated Platform Support. IMAGEHLP_SYMBOL is defined as follows in DbgHelp.h.

#if !defined(_IMAGEHLP_SOURCE_) && defined(_IMAGEHLP64)
 #define IMAGEHLP_SYMBOL IMAGEHLP_SYMBOL64
 #define PIMAGEHLP_SYMBOL PIMAGEHLP_SYMBOL64
#else
 typedef struct _IMAGEHLP_SYMBOL {
     DWORD SizeOfStruct; 
     DWORD Address; 
     DWORD Size; 
     DWORD Flags;  
     DWORD MaxNameLength; 
     CHAR  Name[1];  
 } IMAGEHLP_SYMBOL, *PIMAGEHLP_SYMBOL;
#endif
