Hi,

is there any way to convert this to gmtime_s??

// getDateTime (Fri, 10 Oct 2008 14:41:59 GMT)
string getDateTime(void)
{
time_t rawtime;
struct tm * timeinfo;
time(&rawtime);
timeinfo = gmtime(&rawtime);
char buffer[30];
strftime(buffer,30,"%a, %d %b %Y %X GMT",timeinfo);
return static_cast<string>(buffer);
}

I cannot work out why VC++ is throwing so many warnings about that!

thanks

string getDateTime(void)
{
time_t rawtime;
struct tm timeinfo;
time(&rawtime);
gmtime_s(&timeinfo, &rawtime);
char buffer[30];
strftime(buffer, 30, "%a, %d %b %Y %X GMT", &timeinfo);
return static_cast<string>(buffer);
}

I don't know what C++ library you're using, so I don't know whether
string is an object or not, but just to be on the safe side I should
point out that if it's typedef'd to a char* you will end up with a world
of fail here.

I just left that part from the original snippet, since the question was
regarding gmtime_s ....

Sorry, missnip on my part --- wasn't meaning to lecture you.
