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);
