This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

.Dt CFTIME 3
|
|
.Sh NAME
|
|
.Nm cftime
|
|
.Nm ascftime
|
|
.Nd convert date and time to string
|
|
.Sh SYNOPSIS
|
|
.Fd #include <time.h>
|
|
.Ft int
|
|
.Fn cftime "char *s" "char *format" "const time_t *clock" ;
|
|
.Ft int
|
|
.Fn ascftime "char *s" "const char *format" "const struct tm *tmptr" ;
|
|
.Sh DESCRIPTION
|
|
.Bf -symbolic
|
|
The cftime and ascftime functions are made obsolete by strftime(3).
|
|
.br
|
|
They are available from the compatibility library, libcompat.
|
|
.Ef
|
|
.Pp
|
|
Use of the functions
|
|
.Nm cftime
|
|
and
|
|
.Nm ascftime
|
|
is strongly deprecated, since there is no way to check for a buffer
|
|
overflow condition. Use
|
|
.Xr strftime 3
|
|
instead.
|
|
|
|
.Nm Ascftime
|
|
is almost identical with
|
|
.Xr strftime 3 ,
|
|
with the only exception there's no parameter to tell about the
|
|
maximal buffer length, and the
|
|
.Fa format
|
|
parameter defaults to
|
|
.Dq %C
|
|
if a
|
|
.Em NULL
|
|
pointer is given.
|
|
|
|
.Nm Cftime
|
|
does the same job, but it first invokes
|
|
.Xr localtime 3
|
|
in order to convert the given
|
|
.Fa clock ,
|
|
then also performs the conversions as requested by the
|
|
.Fa format
|
|
argument.
|
|
|
|
.Sh RETURN VALUES
|
|
The
|
|
.Nm cftime
|
|
and
|
|
.Nm ascftime
|
|
functions return the number of characters written to the output
|
|
buffer
|
|
.Fa s ,
|
|
not counting the trailing null character.
