long dostounix(struct date *d, struct time *t);

Description

dostounix converts a date and time as returned from getdate and gettime into UNIX time format. d points to a date structure, and t points to a time structure containing valid date and time information.

The date and time must not be earlier than or equal to Jan 1 1980 00:00:00.

Return Value

Returns UNIX version of current date and time parameters: number of seconds since 00:00:00 on January 1, 1970 (GMT).

Example

 #include <time.h>
 #include <stddef.h>
 #include <dos.h>
 #include <stdio.h>
 int main(void)
 {
   time_t t;
   struct time d_time;
   struct date d_date;
   struct tm *local;
   getdate(&d_date);
   gettime(&d_time);
   t = dostounix(&d_date, &d_time);
   local = localtime(&t);
   printf("Time and Date: %s\n", asctime(local));
   return 0;
 }
