Gnulib module: stat
|
|
|
|
Portability problems fixed by Gnulib:
|
|
@itemize
|
|
@item
|
|
On platforms where @code{off_t} is a 32-bit type, @code{stat} may not correctly
|
|
report the size of files or block devices larger than 2 GB.
|
|
(Cf. @code{AC_SYS_LARGEFILE}.)
|
|
@item
|
|
The @code{st_atime}, @code{st_ctime}, @code{st_mtime} fields are affected by
|
|
the current time zone and by the DST flag of the current time zone on some
|
|
platforms:
|
|
mingw, MSVC 14 (when the environment variable @code{TZ} is set).
|
|
@item
|
|
On MSVC 14, this function fails with error @code{ENOENT}
|
|
on files such as @samp{C:\pagefile.sys} and
|
|
on directories such as @samp{C:\System Volume Information}.
|
|
@item
|
|
On some platforms, @code{stat("link-to-file/",buf)} succeeds instead
|
|
of failing with @code{ENOTDIR}.
|
|
FreeBSD 7.2, AIX 7.1, Solaris 9, mingw64.
|
|
@item
|
|
On some platforms, @code{stat(".",buf)} and @code{stat("./",buf)} give
|
|
different results:
|
|
mingw, MSVC 9.

Portability problems not fixed by Gnulib:

@xref{sys/stat.h}, for general portability problems with @code{struct stat}.
|
|
@item
|
|
Cygwin's @code{stat} function sometimes sets @code{errno} to @code{EACCES} when
|
|
@code{ENOENT} would be more appropriate.
|
|
@item
|
|
Because of the definition of @code{struct stat}, it is not possible to
|
|
portably replace @code{stat} via an object-like macro. Therefore,
|
|
expressions such as @code{(islnk ? lstat : stat) (name, buf)} are not
|
|
portable, and should instead be written @code{islnk ? lstat (name,
|
|
buf) : stat (name, buf)}.
