关于DVRRDK的问题5
各位高手,小弟正在阅读TI为8168处理器提供的DVRRDK软件开发包。阅读过程中遇到以下这个结构体:typedef struct VcapVencVdecVdis_IpcBitsCtrlFileObj {
FILE *fpWrHdr[MCFW_IPC_BITS_MAX_NUM_CHANNELS];
FILE *fpWrData[MCFW_IPC_BITS_MAX_NUM_CHANNELS];
FILE *fpWrMvData[MCFW_IPC_BITS_MAX_NUM_CHANNELS];
char fileDirPath[MCFW_IPC_BITS_MAX_PATH_LENGTH];
Bool wrapOccuredHdr[MCFW_IPC_BITS_MAX_NUM_CHANNELS];
Bool wrapOccuredBuf[MCFW_IPC_BITS_MAX_NUM_CHANNELS];
UInt32 maxFileSize;
Bool enableFWrite;
UInt32 fwriteEnableBitMask;
} VcapVencVdecVdis_IpcBitsCtrlFileObj;
请教其中wrapOccuredBuf成员的含义?以及wrapOccuredBuf成员与wrapOccuredHdr成员的区别?谢谢!
