capFileSetInfoChunk macro (vfw.h)

The capFileSetInfoChunk macro sets and clears information chunks. Information chunks can be inserted in an AVI file during capture to embed text strings or custom data. You can use this macro or explicitly call the WM_CAP_FILE_SET_INFOCHUNK message.

Syntax

void capFileSetInfoChunk(
   hwnd,
   lpInfoChunk
);

Parameters

hwnd

Handle to a capture window.

lpInfoChunk

Pointer to a CAPINFOCHUNK structure defining the information chunk to be created or deleted.

Return value

None

Remarks

Multiple registered information chunks can be added to an AVI file. After an information chunk is set, it continues to be added to subsequent capture files until either the entry is cleared or all information chunk entries are cleared. To clear a single entry, specify the information chunk in the fccInfoID member and NULL in the lpData member of the CAPINFOCHUNK structure. To clear all entries, specify NULL in fccInfoID.
