.TH LIBSIMPLE_GMTIME 3 libsimple
.SH NAME
libsimple_gmtime \- get the current UTC time with leap second adjustment
.SH SYNOPSIS
.nf
#include <libsimple.h>
int libsimple_gmtime(struct tm *\fItm\fP, struct timespec *\fIts\fP);
static inline void libsimple_engmtime(int \fIstatus\fPstruct tm *\fItm\fP, struct timespec *\fIts\fP);
static inline void libsimple_egmtime(struct tm *\fItm\fP, struct timespec *\fIts\fP);
.fi
.PP
Link with
.IR \-lsimple .
.SH DESCRIPTION
The
.BR libsimple_gmtime (),
.BR libsimple_engmtime (),
and
.BR libsimple_egmtime ()
functions get the current UTC time, with adjustments
for leap seconds insertions and deletions.
.PP
The
.BR libsimple_engmtime ()
and
.BR libsimple_egmtime ()
functions will terminate the process on failure.
On failure, the process's exit value will be
.I status
if the
.BR libsimple_engmtime ()
function is used or
.IR libsimple_default_failure_exit (3)
if the
.BR libsimple_egmtime ()
fucntion is used.
.PP
The local time is stored in
.IR *tm ,
and the POSIX time (not timezone adjusted),
with leap second adjustments, is stored in
.I *ts
unless
.I ts
is
.IR NULL .
.I tm
may
.I not
be
.RI NULL .
.SH RETURN VALUE
The
.BR libsimple_gmtime ()
function return a 0 upon successful completion;
otherwise the they return -1 and set
.I errno
to indicate the error. The
.BR libsimple_engmtime ()
and
.BR libsimple_egmtime ()
functions terminate the processes on failure.
.SH ERRORS
The
.BR libsimple_gmtime ()
function will fail for the reasons specified for the
.BR gmtime_r (3)
function.
.PP
The
.BR libsimple_engmtime ()
and
.BR libsimple_egmtime ()
functions will terminate the process on failure.
