AMVABUFFERINFO Structure

The AMVABUFFERINFO structure describes buffer information.

  • Note   This structure is available in Microsoft® Windows® 98 Second Edition, Windows 2000, and later operating systems.

Syntax

typedef struct _tag_AMVABUFFERINFO{
    DWORD dwTypeIndex;
    DWORD dwBufferIndex;
    DWORD dwDataOffset;
    DWORD dwDataSize;
 } AMVABUFFERINFO, *LPAMVABUFFERINFO;

Members
