UnmapDebugInformation function

Deallocates the memory and resources allocated by a call to the MapDebugInformation function.

Note  This function is provided only for backward compatibility. New applications should use the SymUnloadModule64 function.

Syntax


BOOL WINAPI UnmapDebugInformation(
  _In_  PIMAGE_DEBUG_INFORMATION DebugInfo
);

Parameters

DebugInfo [in]

A pointer to an IMAGE_DEBUG_INFORMATION structure that is returned from a call to MapDebugInformation.

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 UnmapDebugInformation function is the counterpart to the MapDebugInformation function and must be used to deallocate the memory and resources allocated by a call to the MapDebugInformation function.

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.

Requirements

Redistributable

DbgHelp.dll 5.1 or later

Header

Dbghelp.h

Library

Dbghelp.lib

DLL

Dbghelp.dll
