I have got a C file in which I would like to add an include statement of my own.
There are already a few include statements and mine should come right after the last existing one (to be neat).
With grep I can get the lines containing the word 'include' and I guess I should feed the... (7 Replies)

timegm
TIMEGM(3) Linux Programmer's Manual TIMEGM(3)NAME
timegm, timelocal - inverses for gmtime and localtime
SYNOPSIS
#include <time.h>
time_t timelocal (struct tm *tm);
time_t timegm (struct tm *tm);
DESCRIPTION
The functions timelocal() and timegm() are the inverses to localtime(3) and gmtime(3).
NOTES
These functions are GNU extensions. The timelocal() function is equivalent to the POSIX standard function mktime(3). There is no reason
to ever use it.
For a portable version of timegm(), set the TZ environment variable to UTC, call mktime() and restore the value of TZ. Something like
#include <time.h>
#include <stdlib.h>
time_t my_timegm (struct tm *tm) {
time_t ret;
char *tz;
tz = getenv("TZ");
setenv("TZ", "", 1);
tzset();
ret = mktime(tm);
if (tz)
setenv("TZ", tz, 1);
else
unsetenv("TZ");
tzset();
return ret;
}
