c - Cross platform method of getting abbreviated weekday name

Question

#include <langinfo.h>
#include <stdio.h>

int main(int argc, char **argv){

char *firstDayAb;
firstDayAb = nl_langinfo(ABDAY_1);
printf("\nFirst day ab is %s\n", firstDayAb);

return 0;
}

This code works fine on Mac and Linux but it doesn't work on windows due to absence of langinfo.h. How to avoid using langinfo.h? Or maybe there is another way of getting abbreviated weekday name?

Answer 1

#include <stdio.h>
#include <time.h>

int main ()
{
  struct tm timeinfo = {0};
  char buffer [80];
  timeinfo.tm_wday = 1;
  strftime (buffer, 80, "First day ab is %a", &timeinfo);
  puts (buffer);      
  return 0;
}
