5 POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/stat.html}
9 Portability problems fixed by Gnulib:
12 On platforms where @code{off_t} is a 32-bit type, @code{stat} may not correctly
13 report the size of files or block devices larger than 2 GB.
14 (Cf. @code{AC_SYS_LARGEFILE}.)
16 The @code{st_atime}, @code{st_ctime}, @code{st_mtime} fields are affected by
17 the current time zone and by the DST flag of the current time zone on some
19 mingw, MSVC 14 (when the environment variable @code{TZ} is set).
21 On MSVC 14, this function fails with error @code{ENOENT}
22 on files such as @samp{C:\pagefile.sys} and
23 on directories such as @samp{C:\System Volume Information}.
25 On some platforms, @code{stat("link-to-file/",buf)} succeeds instead
26 of failing with @code{ENOTDIR}.
27 FreeBSD 7.2, AIX 7.1, Solaris 9, mingw64.
29 On some platforms, @code{stat(".",buf)} and @code{stat("./",buf)} give
33 On Solaris 11.4, when this function yields a timestamp with a
34 nonpositive @code{tv_sec} value, @code{tv_nsec} might be in the range
35 @minus{}1000000000..@minus{}1, representing a negative nanoseconds
36 offset from @code{tv_sec}.
39 Portability problems not fixed by Gnulib:
42 @xref{sys/stat.h}, for general portability problems with @code{struct stat}.
44 Cygwin's @code{stat} function sometimes sets @code{errno} to @code{EACCES} when
45 @code{ENOENT} would be more appropriate.
47 Because of the definition of @code{struct stat}, it is not possible to
48 portably replace @code{stat} via an object-like macro. Therefore,
49 expressions such as @code{(islnk ? lstat : stat) (name, buf)} are not
50 portable, and should instead be written @code{islnk ? lstat (name,
51 buf) : stat (name, buf)}.
