@node clock_getres @subsection @code{clock_getres} @findex clock_getres POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9799919799/functions/clock_getres.html} Gnulib module: --- Portability problems fixed by Gnulib: @itemize @end itemize Portability problems not fixed by Gnulib: @itemize @item This function is missing on some platforms: Mac OS X 10.11, Minix 3.1.8, mingw, MSVC 14. @item On many platforms, this function returns a value other than the clock resolution of @code{clock_gettime}, i.e., the minimum distance between differing timestamps. For example, on AIX 7.2 it returns 10 milliseconds even though the clock resolution is 1 microsecond. Conversely, on GNU/Linux it typically returns 1 nanosecond even though the clock resolution may be greater. @end itemize @mindex gettime-res The Gnulib module @code{gettime-res} is a partial substitute; it implements the @code{CLOCK_REALTIME} functionality of @code{clock_getres}, and fixes the too-high resolution bug of platforms like AIX 7.2.
