|
* Copyright (c) 1989-1993, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* defines time() - gets the current system time and converts it to
|
|
* internal (time_t) format time.
|
|
*
|
|
*Revision History:
|
|
* 06-07-89 PHG Module created, based on asm version
|
|
* 03-20-90 GJF Made calling type _CALLTYPE1, added #include
|
|
* <cruntime.h> and fixed the copyright. Also, cleaned
|
|
* up the formatting a bit.
|
|
* 07-25-90 SBM Removed '32' from API names
|
|
* 10-04-90 GJF New-style function declarator.
|
|
* 12-04-90 SRW Changed to include <oscalls.h> instead of <doscalls.h>
|
|
* 12-06-90 SRW Added _CRUISER_ and _WIN32 conditionals.
|
|
* 05-19-92 DJM ifndef for POSIX build.
|
|
* 03-30-93 GJF Replaced dtoxtime() reference by __gmtotime_t. Also
|
|
* purged Cruiser support.

*time_t time(timeptr) - Get current system time and convert to time_t value.
|
|
*
|
|
*Purpose:
|
|
* Gets the current date and time and stores it in internal (time_t)
|
|
* format. The time is returned and stored via the pointer passed in
|
|
* timeptr. If timeptr == NULL, the time is only returned, not stored in
|
|
* *timeptr. The internal (time_t) format is the number of seconds since
|
|
* 00:00:00, Jan 1 1970 (UTC).
|
|
*
|
|
*Entry:
|
|
* time_t *timeptr - pointer to long to store time in.
|
|
*
|
|
*Exit:
|
|
* returns the current time.
