EXAMPLES The following example uses nl_langinfo() to obtain the date and time format for the current locale: #include <time.h> #include <langinfo.h> #include <locale.h> int main(void) { char datestring[100]; struct tm *tm; time_t t; char *ptr; t = time(NULL); tm = localtime(&t); (void)setlocale(LC_ALL, ""); ptr = nl_langinfo(D_T_FMT); strftime(datestring, sizeof(datestring), ptr, tm); printf("%s\n", datestring); return (0); } SEE ALSO setlocale(3), tm(3), nls(7) STANDARDS The nl_langinfo() function conforms to IEEE Std 1003.1-2001 ("POSIX.1").
