 |
|
I am using:
strptime("2007-03-16 13:14:15","%Y-%m-%d %T",&tmTime);
strftime(szMsg,40,"%Y-%m-%d %T %I%p",&tmTime);
szMsg = "2007-03-16 13:14:15 01PM" which is expected but I don't want
the leading '0' in '01PM' so I tried using the information in the help file
which indicates the usage of '# 'to eliminate the '0' as per:
strftime(szMsg,40,"%Y-%m-%d %T %#I%p",&tmTime);
but I still get:
szMsg = "2007-03-16 13:14:15 01PM"
how do I get rid of the leading '0' in '01PM' ?
As an aside what is the "flag" that is referred to with respect to "%#p"
in strftime?

Also,
strptime("2007-03-16 4:14:15PM","%Y-%m-%d %I:%M:%S%p",&tmTime);
this doesn't work unless there is a space before the 'PM' like so:
strptime("2007-03-16 4:14:15 PM","%Y-%m-%d %I:%M:%S %p",&tmTime);
Is that the way it is supposed to work, if so, where in the
documentation does it say so?

Yes
Where is the related documentation, help files, etc that describe that |
this is the way it is supposed to work for BCB 6? |

As you can see from the following, nothing relevant, at least that I can |
see:
Header File
time.h
Category
Time and Date Routines
Prototype
size_t strftime(char *s, size_t maxsize, const char *fmt, const struct
tm *t);
size_t wcsftime(wchar_t *s, size_t maxsize, const wchar_t *fmt, const
struct tm *t);
Description
Formats time for output.
strftime formats the time in the argument t into the array pointed to by
the argument s according to the fmt specifications. All ordinary
characters are copied unchanged. No more than maxsize characters are
placed in s.
The time is formatted according to the current locale's LC_TIME category.
Return Value
On success, strftime returns the number of characters placed into s.
On error (if the number of characters required is greater than maxsize),
strftime returns 0.
The following table describes the ANSI-defined specifiers for the format
string used with strftime.
