getting CLOCK_TICK_RATE value in linux -

-

I am trying to print the value of CLOCK_TICK_RATE with the following program: 

  #include & lt; Fcntl.h & gt; # Include & lt; Getopt.h & gt; # Include & lt; Signal.h & gt; # Include & lt; Stdio.h & gt; # Include & lt; Stdlib.h & gt; #include & lt; String.h & gt; # Include & lt; Unistd.h & gt; # Include & lt; Sys / ioctl.h & gt; # Include & lt; Sys / types.h & gt; #include & lt; Linux / kd.h & gt; #include & lt; Linux / timex.h & gt; Int main () {printf ("% d \ n", CLOCK_TICK_RATE); }

I get a compilation error:

Error: 'CLOCK_TICK_RATE' undeclared.

I looked for the definition of CLOCK_TICK_RATE, I found in Timex.h, but when I included the time x.h, CLOCK_TICK_RATE still got undeclared.

Thanks in advance.

Maybe you're looking for it? 

  #include & lt; Stdio.h & gt; # Include & lt; Unistd.h & gt; Int main (zero) {printf ("% ld \ n", sysconf (_SC_CLK_TCK)); Return 0; }

It is in Hertz and is generally 100.

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
