Directories

• Creation

  •        #include <sys/stat.h>
           #include <sys/types.h>
    
           int mkdir(const char *pathname, mode_t mode);
           
• Deletion

  •        #include <unistd.h>
           int rmdir(const char *pathname);
    	

  • Only works on directories.
  • And then only on empty directories.
• The remove library function

  •        #include <stdio.h>
           int remove(const char *pathname);
            

  • Calls the correct remove (rmdir or unlink)
• Reading directories
  • Open

    •        #include <sys/types.h>
             #include <dirent.h>
      
             DIR *opendir(const char *name);
             DIR *fdopendir(int fd);
      
             struct dirent {
                 ino_t d_ino;
      	   char d_name[];
             }
      	    

  • Read

    •        #include <dirent.h>
      
             struct dirent *readdir(DIR *dirp);
      	   

  • Rewind and close

    •        #include <sys/types.h>
             #include <dirent.h>
      
             void rewinddir(DIR *dirp);
             int closedir(DIR *dirp);
