EnumMetaFileProc callback function
The EnumMetaFileProc function is an application-defined callback function that processes Windows-format metafile records. This function is called by the EnumMetaFile function. The MFENUMPROC type defines a pointer to this callback function. EnumMetaFileProc is a placeholder for the application-defined function name.
Note This function is provided only for compatibility with Windows-format metafiles. Enhanced-format metafiles provide superior functionality and are recommended for new applications. The corresponding function for an enhanced-format metafile is EnhMetaFileProc.
int CALLBACK EnumMetaFileProc( _In_ HDC hDC, _In_ HANDLETABLE *lpHTable, _In_ METARECORD *lpMFR, _In_ int nObj, _In_ LPARAM lpClientData );
Handle to the device context passed to EnumMetaFile.
Pointer to a table of handles associated with the graphics objects (pens, brushes, and so on) in the metafile.
Pointer to one of the records in the metafile. This record should not be modified. (If modification is necessary, it should be performed on a copy of the record.)
Specifies the number of objects with associated handles in the handle table.
Pointer to optional data.
This function must return a nonzero value to continue enumeration; to stop enumeration, it must return zero.
An application must register the callback function by passing its address to the EnumMetaFile function.
EnumMetaFileProc is a placeholder for the application-supplied function name.
