Convert a struct tm item to a time_t type.

This function is compatible with the following targets:

ANSI

BeOS

EMB/RTOS

Mac OS

Palm OS

Win32

#include <time.h>

time_t mktime(struct tm *timeptr);

Parameters for this facility are:

timeptr

struct tm *

The address of the tm structure

The mktime() function converts a struct tm type and returns it as a time_t type.

The function also adjusts the fields in timeptr if necessary. The tm_sec, tm_min, tm_hour, and tm_day are processed such that if they are greater than their maximum, the appropriate carry-overs are computed. For example, if timeptr->tm_min is 65, timeptr->tm_hour will be incremented by 1 and timeptr->min will be set to 5.

The function also computes the correct values for timeptr->tm_wday and timeptr->tm_yday.

mktime() returns the converted tm structure as a time_t type.
