I searched dirent to find C routines 



find / -iregex ".*/dirent.h$" 2>/dev/null


Which return series of identical ones



/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/dirent.h

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/sys/dirent.h

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Kernel.framework/Versions/A/Headers/sys/dirent.h

/Applications/Xcode.app/Contents/Developer/Platforms/AppleTVOS.platform/Developer/SDKs/AppleTVOS.sdk/usr/include/dirent.h


How could I ensure which dirent.h is the one my program invoke?

          If you get the compiler to show you the code after pre-processing, you should be able to work it out.



          So, for example, with gcc, you can write a nominal program.c:



          #include <dirent.h>
          
main(int argc, char **argv){
          
    return 0;
          
}


          And then run:



          gcc -E program.c


          and study what it includes.

FTE is often used to measure a worker's or student's involvement in a project, or to track cost reductions in an organization. An FTE of 1.0 is equivalent to a full-time worker or student, while an FTE of 0.5 signals half of a full work or school load.
