SymRegisterCallback64 Function

Registers a callback function for use by the symbol handler.

This function supersedes the SymRegisterCallback function. For more information, see Updated Platform Support.

BOOL WINAPI SymRegisterCallback64(
  __in          HANDLE hProcess,
  __in          PSYMBOL_REGISTERED_CALLBACK64 CallbackFunction,
  __in          ULONG64 UserContext
);

Parameters

hProcess

A handle to the process that was originally passed to the SymInitialize function.

CallbackFunction

A SymRegisterCallbackProc64 callback function.

UserContext

A user-defined value or NULL. This value is simply passed to the callback function. Normally, this parameter is used by an application to pass a pointer to a data structure that lets the callback function establish some context.

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

The SymRegisterCallback64 function lets an application register a callback function for use by the symbol handler. The symbol handler calls the registered callback function when there is status or progress information for the application.

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.

Requirements

Redistributable	Requires DbgHelp.dll 5.1 or later.
Header	Declared in Dbghelp.h.
Library	Use Dbghelp.lib.
