List of known bugs (certainly very incomplete)

-Time-stamp: <1999-04-19T17:58:10-0700 drepper>
+Time-stamp: <1999-07-06T15:37:11-0700 drepper>
This following list contains those bugs which I'm aware of. Please
make sure that bugs you report are not listed here. If you can fix one
[ *] The libm-ieee `scalb' function gives wrong results for
non-integral second parameters.
-[ *] The *scanf() functions currently do not handle %l[ and %ls parameters
- correctly since the parsing of the multi-byte characters does not
- yet use mbsrtowcs().
-
[ *] The strftime() implementation cannot handle multibyte locales really
good since the TOLOWER and TOUPPER are not prepared.
+[ *] The putenv() function copies it's argument which means that the
+ string (and possible later changes to it) are not automatically
+ reflected in the environment.

@end deftypefun
Unlike @code{mktemp}, @code{mkstemp} is actually guaranteed to create a
create a temporary file. This is because it works by calling
@code{open} with the @code{O_EXCL} flag bit, which says you want to
always create a new file, and get an error if the file already exists.

+@deftypefun {char *} mkdtemp (char *@var{template})
+The @code{mkdtemp} function creates a directory with a unique name. If
+it succeeds, it overwrites @var{template} with the name of the
+directory, and returns @var{template}. As with @code{mktemp} and
+@code{mkstemp}, @var{template} should be a string ending with
+@samp{XXXXXX}.
+
+If @code{mkdtemp} cannot create an uniquely named directory, it returns
+@code{NULL} and sets @var{errno} appropriately. If @var{template} does
+not end with @samp{XXXXXX}, @code{mkdtemp} returns @code{NULL} and does
+not modify @var{template}. @var{errno} will be set to @code{EINVAL} in
+this case.
+
+The directory is created using mode @code{0700}.
+@end deftypefun
+
+The directory created by @code{mkdtemp} cannot clash with temporary
+files or directories created by other users. This is because directory
+creation always works like @code{open} with @code{O_EXCL}.
+@xref{Creating Directories}.

+The @code{mkdtemp} function comes from OpenBSD.
