BusyBox is a multi-call binary that combines many common Unix

utilities into a single executable.  Most people will create a

link to busybox for each function they wish to use and BusyBox

will act like whatever it was invoked as.

可以看见LOGV的打印生效，文件名、行号以及函数名都可以打印出来，但是printf无效。

printf("**** %s-%d-%s \n", __FILE__, __LINE__, __func__);

LOGV("**** %s-%d-%s ", __FILE__, __LINE__, __func__);
