explain_fchmod_or_die(3)   Library Functions Manual   explain_fchmod_or_die(3)

NAME
       explain_fchmod_or_die  -	 change	permissions of an open file and	report
       errors

SYNOPSIS
       #include	<libexplain/fchmod.h>
       void explain_fchmod_or_die(int fildes, mode_t mode);
       int explain_fchmod_on_error(int fildes, mode_t mode);

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

       The explain_fchmod_on_error function is used to call the	fchmod(2) sys-
       tem call. On failure an explanation will	be printed to stderr, obtained
       from the	explain_fchmod(3) function, but	still returns to the caller.

       fildes  The  fildes,  exactly  as  to be	passed to the fchmod(2)	system
	       call.

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

RETURN VALUE
       The explain_fchmod_or_die function only returns on  success,  see  fch-
       mod(2)  for more	information. On	failure, prints	an explanation and ex-
       its, it does not	return.

       The explain_fchmod_on_error function always returns the value return by
       the wrapped fchmod(2) system call.

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