Function Documentation

void explain_buffer_errno_stat	(	struct explain_string_buffer_t *	sb,
		int	errnum,
		const char *	path,
		const struct stat *	stp
	)

The explain_buffer_errno_stat function is used to obtain an explanation of an error returned by the stat(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 in which the message is being constructed. If a safe buffer is specified, this function is thread safe.
errnum	The error value to be decoded, usually obtain 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.
path	The original path, exactly has passed to the stat(2) system call.
stp	The original stp, exactly has passed to the stat(2) system call.

void explain_buffer_errno_stat_explanation	(	struct explain_string_buffer_t *	sb,
		int	errnum,
		const char *	syscall_name,
		const char *	path,
		const struct stat *	stp
	)

The explain_buffer_errno_stat_explanation function is used to write the explanation (after "because") of an error returned by the stat(2) system call.

Parameters:

sb	The string buffer in which the message is being constructed. If a safe buffer is specified, this function is thread safe.
errnum	The error value to be decoded, usually obtain 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 offended system call.
path	The original path, exactly has passed to the stat(2) system call.
stp	The original stp, exactly has passed to the stat(2) system call.
