                                                                                        explain_lchmod_or_die(3)

       The  explain_lchmod_or_die  function is used to call the lchmod(2) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_lchmod(3) function, and then the process  terminates
       by calling exit(EXIT_FAILURE).

       The explain_lchmod_on_error function is used to call the lchmod(2) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_lchmod(3) function, but still returns to the caller.

       pathname
               The pathname, exactly as to be passed to the lchmod(2) system call.

       mode    The mode, exactly as to be passed to the lchmod(2) system call.

       The explain_lchmod_or_die function is intended to be used in a fashion similar to the following example:
              explain_lchmod_or_die(pathname, mode);

       explain_lchmod_or_die - change permissions of a file and report errors

       The  explain_lchmod_or_die  function  only  returns  on  success,  see lchmod(2) for more information. On
       failure, prints an explanation and exits, it does not return.

       The explain_lchmod_on_error function always returns the value return  by  the  wrapped  lchmod(2)  system
       call.

lchmod(2)
               change permissions of a file

       explain_lchmod(3)
               explain lchmod(2) errors

       exit(2) terminate the calling process

       #include <libexplain/lchmod.h>
       void explain_lchmod_or_die(const char *pathname, mode_t mode);
       int explain_lchmod_on_error(const char *pathname, mode_t mode);
