dostounix

raw OCR

Converts date and time to UNIX time format.

Defined in header <dos.h>

Syntax

#include <dos.h>
long  dostounix(struct      date  *d, struct  time   *t);

   DOS     UNIX     Windows   ANSI C    C++ only
     ■                 ■

Remarks

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

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

Retum value

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