Format
#include <wchar.h> int wprintf(const wchar_t *format,...);
Language Level: ANSI 93
wprintf(format, ... ) is equivalent to fwprintf(stdout, format,
... ).
For a complete description, see fwprintf -- Format Data as Wide Characters and Write to a Stream.
Return Value
wprintf returns the number of wide characters
transmitted.
If an output error occurred, wprintf returns a negative value.
Example
This example prints date and time in the form "Monday, April
14, 17:47" followed by pi to five decimal places. Note that
date and time may be formatted according to your locale's
representation. The output goes to stdout.
#include <stdlib.h> #include <stdio.h> #include <math.h> #include <time.h> #include <wchar.h> #include <locale.h>
int main(void)
{
wchar_t *weekday, *month;
struct tm *newtime;
time_t ltime;
struct dtconv *p;
weekday = (wchar_t *)malloc(sizeof(wchar_t)*20); month = (wchar_t *)malloc(sizeof(wchar_t)*20);
setlocale(LC_ALL,"");
time(<ime); newtime = localtime(<ime); p = localdtconv(); mbstowcs(weekday, p->day_names[newtime->tm_wday], sizeof(wchar_t)*20); mbstowcs(month, p->month_names[newtime->tm_mon], sizeof(wchar_t)*20);
wprintf(L"%ls, %ls %d, %.2d:%.2d\n",
weekday, month, newtime->tm_mday,
newtime->tm_hour, newtime->tm_min);
wprintf(L"pi = %.5f\n", 4* atan(1.0));
return 0;
