FormatDate -- generate a date string based on a date formatting
template. (V38)
FormatDate(locale,fmtTemplate,date,putCharFunc);
A0 A1 A2 A3
VOID FormatDate(struct Locale *,STRPTR,struct DateStamp *,
struct Hook *);
This function processes a formatting template and generates
a stream of bytes that's sent one character at a time to the
putCharFunc callback hook.
locale - the locale to use for the formatting
fmtTemplate - the NULL-terminated template describing the desired
format for the date. This is constructed just like
C-language printf() statements, except that different
formatting codes are used. Just like in C, formatting
codes start with a % followed by the formatting command.
The following commands are accepted by this function:
%a - abbreviated weekday name
%A - weekday name
%b - abbreviated month name
%B - month name
%c - same as "%a %b %d %H:%M:%S %Y"
%C - same as "%a %b %e %T %Z %Y"
%d - day number with leading 0s
%D - same as "%m/%d/%y"
%e - day number with leading spaces
%h - abbreviated month name
%H - hour using 24-hour style with leading 0s
%I - hour using 12-hour style with leading 0s
%j - julian date
%m - month number with leading 0s
%M - the number of minutes with leading 0s
%n - insert a linefeed
%p - AM or PM strings
%q - hour using 24-hour style
%Q - hour using 12-hour style
%r - same as "%I:%M:%S %p"
%R - same as "%H:%M"
%S - number of seconds with leadings 0s
%t - insert a tab character
%T - same as "%H:%M:%S"
%U - week number, taking Sunday as first day of week
%w - weekday number
%W - week number, taking Monday as first day of week
%x - same as "%m/%d/%y"
%X - same as "%H:%M:%S"
%y - year using two digits with leading 0s
%Y - year using four digits with leading 0s
If the template parameter is NULL, a single NULL byte
is sent to putCharFunc.
date - the date to format into a string
putCharFunc - a callback hook invoked for every character generated,
including for the terminating NULL character. The hook
is called with:
A0 - address of Hook structure
A1 - character for hook to process (not a pointer!)
A2 - locale pointer
