@node lstat @section @code{lstat} @findex lstat POSIX specification: @url{http://www.opengroup.org/onlinepubs/9699919799/functions/lstat.html} Gnulib module: lstat Portability problems fixed by Gnulib: @itemize @item For symlinks, when the argument ends in a slash, some platforms don't dereference the argument: Solaris 9. @item On some platforms, @code{lstat("file/",buf)} succeeds instead of failing with @code{ENOTDIR}. Solaris 9. @item On Windows platforms (excluding Cygwin), symlinks are not supported, so @code{lstat} does not exist. @end itemize Portability problems not fixed by Gnulib: @itemize @item On platforms where @code{off_t} is a 32-bit type, @code{lstat} may not correctly report the size of files or block devices larger than 2 GB. The fix is to use the @code{AC_SYS_LARGEFILE} macro. @item On Windows platforms (excluding Cygwin), @code{st_ino} is always 0. @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)}. @item On some file systems, @code{st_size} contains bogus information for symlinks; use the gnulib module areadlink-with-size for a better way to get symlink contents. @end itemize
