NAME

       explain_fchownat_or_die  -  change  ownership  of  a  file relative to a directory     and
       report errors

SYNOPSIS

       #include <libexplain/fchownat.h>
       void explain_fchownat_or_die(int dirfd, const char *pathname, int owner,  int  group,  int
       flags);
       int  explain_fchownat_on_error(int  dirfd, const char *pathname, int owner, int group, int
       flags);

DESCRIPTION

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

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

       dirfd   The dirfd, exactly as to be passed to the fchownat(2) system call.

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

       owner   The owner, exactly as to be passed to the fchownat(2) system call.

       group   The group, exactly as to be passed to the fchownat(2) system call.

       flags   The flags, exactly as to be passed to the fchownat(2) system call.

RETURN VALUE

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

       The  explain_fchownat_on_error  function  always  returns  the value return by the wrapped
       fchownat(2) system call.

EXAMPLE

       The explain_fchownat_or_die function is intended to be used in a fashion  similar  to  the
       following example:
              explain_fchownat_or_die(dirfd, pathname, owner, group, flags);
