it seems that vc6 does not support va args macro.

otherwise the function name, line, file are wrong

typdef struct append {
void *opaq;
append_func callback;
}

it will be more flexible

define qDebug(...) ezlog_qt(FILE, ....).print()
what about qDebug() << xxx
class ezlog_qt {

}
operator <<

android need additional parameters in ctor
define android_log(...) ezlog_android(TAG, LEVEL, __FILE,....)
class ezlog_android {

}

define ezlog_debug(fmt, ...)

EZLOG_FILE
EZLOG_LAYOUT

do not affect the original thread

loop log task queue in a thread

now is global, can we use a smaller scope? mutex in struct? set null mutex in ezlog ?

like ffmpeg lockmgr. null means no lock, then user can use scoped lock outside instread of global lock.

remove ezmutex?

tst_ezlog/main.c

add macro in makefiles and link to ezlog++

e.g. red for error, white for debug

BOOL SetConsoleTextAttribute( HANDLE hConsoleOutput,WORD wAttributes);
