Function Documentation

int explain_fchown_on_error	(	int	fildes,
		int	owner,
		int	group
	)

The explain_fchown_on_error function is used to call the fchown(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_fchown(3) function.

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

 if (explain_fchown_on_error(fildes, owner, group) < 0)
 {
     ...cope with error
     ...no need to print error message
 }

Parameters:

fildes	The fildes, exactly as to be passed to the fchown(2) system call.
owner	The owner, exactly as to be passed to the fchown(2) system call.
group	The group, exactly as to be passed to the fchown(2) system call.

Returns:

The value returned by the wrapped fchown(2) system call.
