Function Documentation

void explain_buffer_errno_kill	(	explain_string_buffer_t *	sb,
		int	errnum,
		pid_t	pid,
		int	sig
	)

The explain_buffer_errno_kill function is used to obtain an explanation of an error returned by the kill(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 suitable 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.
pid	The original pid, exactly as passed to the kill(2) system call.
sig	The original sig, exactly as passed to the kill(2) system call.

void explain_buffer_errno_kill_explanation	(	explain_string_buffer_t *	sb,
		int	errnum,
		const char *	syscall_name,
		pid_t	pid,
		int	sig
	)

The explain_buffer_errno_kill_explanation function is used to print an explanation (the text after "basecase") of an error returned by the kill(2) system call.

Parameters:

sb	The string buffer to print the message into.
errnum	The error value to be decoded.
syscall_name	The name of the offending system call.
pid	The original pid, exactly as passed to the system call.
sig	The original sig, exactly as passed to the system call.
