void explain_buffer_errno_shmctl	(	explain_string_buffer_t *	sb,
		int	errnum,
		int	shmid,
		int	command,
		struct shmid_ds *	data
	)

The explain_buffer_errno_shmctl function is used to obtain an explanation of an error returned by the shmctl(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.
shmid	The original shmid, exactly as passed to the shmctl(2) system call.
command	The original command, exactly as passed to the shmctl(2) system call.
data	The original data, exactly as passed to the shmctl(2) system call.

void explain_buffer_errno_shmctl_explanation	(	explain_string_buffer_t *	sb,
		int	errnum,
		const char *	syscall_name,
		int	shmid,
		int	command,
		struct shmid_ds *	data
	)

The explain_buffer_errno_shmctl_explanation function is used to obtain the explanation (the part after "because") of an error returned by the shmctl(2) system call (and similar).

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.
syscall_name	The name of the offending system call.
shmid	The original shmid, exactly as passed to the shmctl(2) system call.
command	The original command, exactly as passed to the shmctl(2) system call.
data	The original data, exactly as passed to the shmctl(2) system call.
