程序示例

// crt_setlocale.cpp

//

// This program demonstrates the use of setlocale when

// using two independent threads.

//

#include <locale.h>

#include <process.h>

#include <windows.h>

#include <stdio.h>

#include <time.h>

#define BUFF_SIZE 100

// Retrieve the date and time in the current

// locale's format.

// Format the current time structure into a string

// using %#x is the long date representation,

// appropriate to the current locale

if (!strftime((char *)str, BUFF_SIZE, "%#x",

}

// This thread sets its locale to German

// and prints the time.

}

}

// The main thread spawns a second thread (above) and then

// sets the locale to English and prints the time.

int main()
