Enumerates all user-defined types.

Syntax

BOOL IMAGEAPI SymEnumTypesW(
  [in]           HANDLE                          hProcess,
  [in]           ULONG64                         BaseOfDll,
  [in]           PSYM_ENUMERATESYMBOLS_CALLBACKW EnumSymbolsCallback,
  [in, optional] PVOID                           UserContext
);

Parameters

[in] hProcess

A handle to a process. This handle must have been previously passed to the SymInitialize function.

[in] BaseOfDll

The base address of the module.

[in] EnumSymbolsCallback

A pointer to an SymEnumSymbolsProc callback function that receives the symbol information.

[in, optional] UserContext

A user-defined value to be passed to the callback function, or NULL. This parameter is typically used by an application to pass a pointer to a data structure that provides context information for the callback function.

Return value

If the function succeeds, the return value is TRUE.

If the function fails, the return value is FALSE. To retrieve extended error information, call GetLastError.

Remarks

All DbgHelp functions, such as this one, are single threaded. Therefore, calls from more than one thread to this function will likely result in unexpected behavior or memory corruption. To avoid this, you must synchronize all concurrent calls from more than one thread to this function.

To call the Unicode version of this function, define DBGHELP_TRANSLATE_TCHAR.

Note

The dbghelp.h header defines SymEnumTypes as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
