Android custom log

The following is a draft of a previously edited custom log. Now, I don't remember the va_list function,

I should have written it clearly at the beginning, and now I am too lazy to read it.

/** My log for trace code */# ifndef mylog # define mylog (...) \ mylog_print (android_log_error, log_tag, _ va_args _) # define mylog_print (PRIO, Tag, FMT ...) \ myprint (PRIO, Tag, FMT) # define log_buf_size 1024 static long myno = 0; static int myprint (INT Prio, const char * tag, const char * FMT ,...) {va_list AP; char * my_tag = "*** it's my log! * ** No. "; int Len; char Buf [log_buf_size]; Len = sprintf (BUF," % S % ld: ", my_tag, myno ++); va_start (AP, FMT ); vsnprintf (BUF + Len, LOG_BUF_SIZE-len, FMT, AP); va_end (AP); Return _ android_log_write (PRIO, Tag, Buf );} # endif/** end my log */
