Function Documentation

void explain_buffer_errno_listen	(	explain_string_buffer_t *	sb,
		int	errnum,
		int	fildes,
		int	backlog
	)

The explain_buffer_errno_listen function is used to obtain an explanation of an error returned by the listen(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.
fildes	The original fildes, exactly as passed to the listen(2) system call.
backlog	The original backlog, exactly as passed to the listen(2) system call.
