SymEnumSymbolsForAddrW function (dbghelp.h)

  • Article

Enumerates the symbols for the specified address.

Syntax

BOOL IMAGEAPI SymEnumSymbolsForAddrW(
  [in]           HANDLE                          hProcess,
  [in]           DWORD64                         Address,
  [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] Address

The address for which symbols are to be located. The address does not have to be on a symbol boundary. If the address comes after the beginning of a symbol and before the end of the symbol (the beginning of the symbol plus the symbol size), the function will find the symbol.

[in] EnumSymbolsCallback

An application-defined callback function. This function is called for every symbol found at Address. For more information, see SymEnumSymbolsProc.

[in, optional] UserContext

Optional user-defined data. This value is passed to 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 SymEnumSymbolsForAddr 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.
