Chapter 18: Directories and Links

Exercise 18-2

The real solution is here.

My solution is in ex18_2.c.

Use make ex18_2 to compile and link the code.
Use ./ex18_2 to execute this solution.

Exercise 18-3

My solution is in realpath.c.

Use make realpath to compile and link this code.
Use ./test_realpath.sh to test this solution.

Exercise 18-4

My solution is in list_files.c.

Use make list_files to compile and link this code.
Use ./list_files to execute this solution.

NOTE: The compilation will give the following messages:

list_files.c: In function ‘listFiles’:
list_files.c:42:9: warning: ‘readdir_r’ is deprecated [-Wdeprecated-declarations]
         if ((readdir_r(dirp, dp, &result) != 0) || (result == NULL))
         ^~
In file included from list_files.c:11:0:
/usr/include/dirent.h:183:12: note: declared here
 extern int readdir_r (DIR *__restrict __dirp,
            ^~~~~~~~~

Exercise 18-5

My solution is in getcwd.c. (Build completed)

Use make getcwd to compile and link this program.
Use ./getcwd to execute this solution.

Exercise 18-6

Solution has already been published. The downloaded file is compiled and executed as follows:

Use make nftw_dir_tree to compile and link this program.
Use ./nftw_dir_tree -d .. to execute this solution.

Exercise 18-7

My solution is in ex18_7.c.

Use make ex18_7 to compile and link the code.
Use ./ex18_7 to execute this solution.
