Thank you.  My confusion is cleared now.  So when I want to
check if a process can chdir to a directory, the following
fragment is good enough?

	if(access("/usr/hoge/adir", AREAD) < 0){
		// error, can't chdir to adir
			:
	}


I thought the following should work at first, hence my question.
	if(chdir("/usr/hoge/adir") < 0){
		// error, can't chdir to adir
			:
	}
