  UINT cbBuffer,          // size of buffer
  LPENHMETAHEADER lpemh   // data buffer
);

FoxPro declaration:

DECLARE INTEGER GetEnhMetaFileHeader In gdi32;
	INTEGER   hemf,;
	INTEGER   cbBuffer,;
	STRING  @ lpemh

Parameters:

hemf [in] Handle to the enhanced metafile for which the header is to be retrieved.

cbBuffer [in] Specifies the size, in bytes, of the buffer to receive the data. Only this many bytes will be copied.

lpemh [out] Pointer to an ENHMETAHEADER structure that receives the header record.
