-/* Log file system related error in key-value format identified by Apple
- * system log (ASL) facility. The key-value pairs are string pointers
- * (char *) and are provided as variable arguments list. A NULL value
- * indicates end of the list.
- *
- * Keys can not contain '[', ']', space, and newline. Values can not
- * contain '[', ']', and newline. If any key-value contains any of the
- * reserved characters, the behavior is undefined. The caller of the
- * function should escape any occurrences of '[' and ']' by prefixing
- * it with '\'.
- *
- * The function takes a message ID which can be used to logically group
- * different ASL messages. Messages in same logical group have same message
- * ID and have information to describe order of the message --- first,
- * middle, or last.
- *
- * The following message IDs have special meaning -
- * FSLOG_MSG_FIRST - This message is the first message in its logical
- * group. This generates a unique message ID, creates two key-value
- * pairs with message ID and order of the message as "First".
- * FSLOG_MSG_LAST - This is really a MASK which should be logically OR'ed
- * with message ID to indicate the last message for a logical group.
- * This also creates two key-value pairs with message ID and order of
- * message as "Last".
- * FSLOG_MSG_SINGLE - This signifies that the message is the only message
- * in its logical group. Therefore no extra key-values are generated
- * for this option.
- * For all other values of message IDs, it regards them as intermediate
- * message and generates two key-value pairs with message ID and order of
- * message as "Middle".
- *
- * Returns -
- * Message ID of the ASL message printed. The caller should use
- * this value to print intermediate messages or end the logical message
- * group.
- * For FSLOG_MSG_SINGLE option, it returns FSLOG_MSG_SINGLE.
