Puzzle about the setlocale Function in Miracle3.0

Puzzle about the setlocale Function in Miracle3.0

[Gewj]

There has a quite strange thing about the setlocale function
in Miracle3.0
(Linux 2.4.21-9.38AX #1 Wed Nov 10 22:00:41 EST 2004 i686
glibc-common-2.3.2-95.20.1AX )

I used the following code in a daemon program and start it in rc3.d

	setlocale(LC_ALL, "ja_JP");
	bindtextdomain("express", "/usr/local/mo");
	textdomain("express");
        //get string from .mo file according to the locale set
        strcpy(myString,gettext("MyID"));

the dir structure of /usr/local/mo is list below:

/usr/local/mo
           -|en_US
                 -|LC_MESSAGES
           -|ja_JP
             -|LC_MESSAGES


where I reboot the machine, gettext("MyID") return its string defined in
 en_US .mo file instead of in ja_JP .mo file
But where I restart the same daemon program after reboot , the same
program works OK.

Can anyone show me some tips to the reason?

thanks in advance.
