@node stat @section @code{stat} @findex stat POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/stat.html} 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 14. @item On Solaris 11.3, when this function yields a timestamp with a nonpositive @code{tv_sec} value, @code{tv_nsec} might be in the range @minus{}1000000000..@minus{}1, representing a negative nanoseconds offset from @code{tv_sec}. @end itemize Portability problems not fixed by Gnulib: @itemize @item @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)}. @end itemize
