EnhMetaFileProc info  Overview  Group

The EnhMetaFileProc function is an application-defined callback function that processes enhanced-format metafile records. This function is called by the EnumEnhMetaFile function.

int CALLBACK EnhMetaFileProc(

    HDC hDC,

// handle to device context

    HANDLETABLE FAR *lpHTable,

// pointer to metafile handle table

    ENHMETARECORD FAR *lpEMFR,

// pointer to metafile record

    int nObj,

// count of objects

    LPARAM lpData 

// pointer to optional data

   );

Parameters

hDC
Identifies the device context passed to EnumEnhMetaFile.
lpHTable
Points to a table of handles associated with the graphics objects (pens, brushes, and so on) in the metafile. The first entry contains the enhanced-metafile handle.
lpEMFR
Points 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
Specifies the number of objects with associated handles in the handle table.
lpData
Points to any application-supplied data.

Return Values

This function must return a nonzero value to continue enumeration; to stop enumeration, it must return zero.

Remarks

An application must register the callback function by passing its address to the EnumEnhMetaFile function.

EnhMetaFileProc is a placeholder for the application-supplied function name.
