宏定义变参printf

#define PRT(...)printf("Filename %s, Function %s, Line %d > ", __FILE__, __FUNCTION__, __LINE__); \

printf(__VA_ARGS__); \

printf("\n");

推荐使用这个宏：

#define DVR_PRT(format,...)printf("[File:"__FILE__", Line:%d]  "format, __LINE__, ##__VA_ARGS__)

#define PRT(format,...)printf("[File:%s, Line:%d] "format, __FILE__, __LINE__, ##__VA_ARGS__)

APP_PLATFORM := android-21

APP_ABI := armeabi-v7a
