Function Documentation

int explain_acl_set_fd_on_error	(	int	fildes,
		acl_t	acl
	)

The explain_acl_set_fd_on_error function is used to call the acl_set_fd(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_acl_set_fd(3) function.

Parameters:

fildes	The fildes, exactly as to be passed to the acl_set_fd(3) system call.
acl	The acl, exactly as to be passed to the acl_set_fd(3) system call.

Returns:

The value returned by the wrapped acl_set_fd(3) system call.

Example:

This function is intended to be used in a fashion similar to the following example:

 if (explain_acl_set_fd_on_error(fildes, acl) < 0)
 {
     ...cope with error
     ...no need to print error message
 }

void explain_acl_set_fd_or_die	(	int	fildes,
		acl_t	acl
	)

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

Parameters:

fildes	The fildes, exactly as to be passed to the acl_set_fd(3) system call.
acl	The acl, exactly as to be passed to the acl_set_fd(3) system call.

This function only returns on success, see acl_set_fd(3) for more information. On failure, prints an explanation and exits, it does not return.

Example:

This function is intended to be used in a fashion similar to the following example:

 explain_acl_set_fd_or_die(fildes, acl);
