@node utime @section @code{utime} @findex utime POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/utime.html} Gnulib module: --- Portability problems fixed by Gnulib: @itemize @end itemize Portability problems not fixed by Gnulib: @itemize @item On some old platforms (Sequent), @code{utime (file, NULL)} fails to set the file's timestamp to the current time. @item On some platforms, this function mis-handles trailing slash: Solaris 9. @item This function cannot set full timestamp resolution. Use @code{utimensat(AT_FDCWD,file,times,0)}, or the gnulib module utimens, instead. @item On some platforms, the prototype for @code{utime} omits @code{const} for the second argument. Fortunately, the argument is not modified, so it is safe to cast away const: mingw, MSVC 9. @end itemize
