&portObjs[chan->portNum] C语言基础知识问答
typedef struct PortObj{/* port status register, contains information on whether */
/* port is opened, configured, etc. */
Int status;//端口状态寄存器 包含端口是否打开,端口配置等等信息
/* vp base address for all register access */
Int base;//视频口所有寄存器入口地址
/* two channel objects for channel A & B.*/
/* This is only for capture operation */
_VPORT_ChanObj chanObj;//通道对象各种参数
} PortObj;
_VPORT_ChanObj* chan = (_VPORT_ChanObj* )chanp;//通道数据结构体指针传递
PortObj* port = &portObjs;
请问各位 &portObjs取的是哪部分的地址???整个人都晕了!!!!!!!!!!!{:funk:}
