I saw somewhere that someone took the computer's current in a whole int,and started calculating hours minutes seconds,and i don't remember what function he used to get the time as an int, maybe inportb or MK_FP or something else,and i don't remember if it was in dos.h.Can someone help me,i tried to find this for some quite time.
In standard C, you can get the current time by calling the time function:
time_t now = time(NULL);
which requires
#include <time.h>
The NULL argument is admittedly odd; it's there for historical reasons.
time_t is a numeric type capable of representing times. The way it does so is implementation-specific, but it's typically an integer representing the number of seconds since January 1, 1970. I'm not certain that Borland uses the same representation; consult your system's documentation for the time function.
<time.h> also provides various functions to convert between time_t values and struct tm (a "broken-down" time), to generate human-readable strings from times, and so forth.
There may be some other way to get the current time, something specific to Borland and/or MS-DOS. But unless you need better than 1-second resolution, or you're using an implementation that's so ancient it doesn't suport the time function properly, there's not much reason to use anything other than the standard time function.
