CAPINFOCHUNK

  • Article

The CAPINFOCHUNK structure contains parameters that can be used to define an information chunk within an AVI capture file. The WM_CAP_FILE_SET_INFOCHUNK message or capSetInfoChunk macro is used to send a CAPINFOCHUNK structure to a capture window.

typedef struct { 
    FOURCC fccInfoID; 
    LPVOID lpData; 
    LONG   cbData; 
} CAPINFOCHUNK;

Members

fccInfoID

Four-character code that identifies the representation of the chunk data. If this value is NULL and lpData is NULL, all accumulated information chunks are deleted.

lpData

Pointer to the data. If this value is NULL, all fccInfoID information chunks are deleted.

cbData

Size, in bytes, of the data pointed to by lpData. If lpData specifies a
null-terminated string, use the string length incremented by one to save the NULL with the string.
