VS2013MFC中这段代码请帮忙详细解释一下

Question

BITMAPINFO *m_pBmpInfo;

char m_chBmpBuf[2048];

m_pBmpInfo= (BITMAPINFO *)m_chBmpBuf

Answer 1

1 BITMAPINFO m_pBmpInfo //创建结构体BITMAPINFO的指针
2 char m_chBmpBuf[2048]; //分配缓冲（内存2048字节）
3 m_pBmpInfo= (BITMAPINFO *)m_chBmpBuf //让指针m_pBmpInfo指向刚刚分配的内存，并强制转换char到BITMAPINFO *指针
