DWORD IMAGEAPI GetImageUnusedHeaderBytes(
  [in]  PLOADED_IMAGE LoadedImage,
  [out] PDWORD        SizeUnusedHeaderBytes
);

Parameters

[in] LoadedImage

A pointer to a LOADED_IMAGE structure that is returned from a call to MapAndLoad or ImageLoad.

[out] SizeUnusedHeaderBytes

A pointer to a variable to receive the size, in bytes, of the part of the image's header which is unused.

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

Remarks

All ImageHlp 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.
