Function Documentation

void explain_buffer_errno_lchown	(	explain_string_buffer_t *	sb,
		int	errnum,
		const char *	pathname,
		int	owner,
		int	group
	)

The explain_buffer_errno_lchown function is used to obtain an explanation of an error returned by the lchown(2) system call. The least the message will contain is the value of strerror(errnum), but usually it will do much better, and indicate the underlying cause in more detail.

Parameters:

sb	The string buffer to print the message into. If a safe buffer is specified, this function is thread safe.
errnum	The error value to be decoded, usually obtained from the errno global variable just before this function is called. This is necessary if you need to call any code between the system call to be explained and this function, because many libc functions will alter the value of errno.
pathname	The original pathname, exactly as passed to the lchown(2) system call.
owner	The original owner, exactly as passed to the lchown(2) system call.
group	The original group, exactly as passed to the lchown(2) system call.
