how to get directory path and name, file path and name from inode
/, /usr/, /var are different physical filesystems. Is it why inode number can be the same across them?...

The reason I am asking all these questions is that I want to find out if there is a way, through inode number (inode.st_ino), I can fnd out file directory path, and file name, or directory path and directory name? Any system functions that I can call to find out? Thank s a lot.

Code:

matchpathcon_checkmatches

matchpathcon_checkmatches(3)				     SELinux API documentation				      matchpathcon_checkmatches(3)

NAME

       matchpathcon_checkmatches,  matchpathcon_filespec_add, matchpathcon_filespec_destroy, matchpathcon_filespec_eval - check and report whether
       any specification index has no matches with any inode. Maintenance and statistics on inode associations.

SYNOPSIS

       #include <selinux/selinux.h>

       void matchpathcon_checkmatches(char *str);

       int matchpathcon_filespec_add(ino_t ino, int specind, const char *file);

       void matchpathcon_filespec_destroy(void);

       void matchpathcon_filespec_eval(void);

DESCRIPTION

       matchpathcon_checkmatches checks whether any specification has no matches and reports them.  The str argument is used as a prefix  for  any
       warning messages.

       matchpathcon_filespec_add maintains an association between an inode ino and a specification index specind, and checks whether a conflicting
       specification is already associated with the same inode (e.g. due to multiple hard links). If so, then it uses the latter of the two speci-
       fications based on their order in the file context configuration. Returns the specification index used or -1 on error.

       matchpathcon_filespec_destroy destroys any inode associations that have been added, e.g. to restart for a new filesystem.

       matchpathcon_filespec_eval displays statistics on the hash table usage for the inode associations.

RETURN VALUE

       Returns zero on success or -1 otherwise.
