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 );
- hDC [in]
Handle to the device context passed to EnumMetaFile.
- lpHTable [in]
Pointer to a table of handles associated with the graphics objects (pens, brushes, and so on) in the metafile.
- lpMFR [in]
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.)
- nObj [in]
Specifies the number of objects with associated handles in the handle table.
- lpClientData [in]
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.
