NAME

       explain_lchmod_or_die - change permissions of a file and report errors

SYNOPSIS

       #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);

DESCRIPTION

       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.

RETURN VALUE

       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.

EXAMPLE

       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);
