tm_wday

[ami]

Hello,

I have :-

...

char formattedDate[13]="";

time_t tim = time(NULL);
tm *now = localtime(&tim);

sprintf(formattedDate, "%02d/%02d/%d", now->tm_mday, now->tm_mon+1, now->tm_year+1900);

and I'm trying to retrieve the day of the week, i.e. tm_wday

I've tried doing:
...
char currentDay[5]="";
sprintf(currentDay, "%s", now->tm_wday);
...
But this results in a core dump.

Can someone please help ?

Thanks,

Imanuel.

The tm_wday seems to contain the ordinal number of the week day (0-6). If you need the short name of the day, you could consider this:

static const char * names[7] = 
{
    "Sun",
    "Mon",
    "Tue",
    "Wed",
    "Thu",
    "Fri",
    "Sat",
};

const char * name = names[now->tm_wday].

I hope this makes sense.

Check data type of now->tm_wday

In addition to what others have proposed, you should replace the following statement:
tm *now = localtime(&tim);
with:
tm now = *localtime(&tim);

And then use the dot notation to access members of now. This will not fix your bug but it will fix other bugs that you may haven't noticed.
