Discussion

%SS_FATAL provides the ability to send a final error packet to the other end of a socket if the program ends before the socket is properly closed. Thus, if a broken socket occurs, the other end of the socket doesn’t have to continue to wait indefinitely.

Message can contain two %s and three %d specifiers. For example,

"some message text %s %s %d %d %d some more message text"

The %s and %d specifiers can occur anywhere in the string and be delimited by any or no characters, but they must be specified in the order shown above. The %s and %d specifiers are replaced with the following, in this order:

You don’t have to use all five specifiers, but if you don’t use them all, you can truncate the string only from the right. For example, “%s %s %d %d”, “%s %s %d”, “%s %s”, and “%s” are all valid, but “%s %d” and “%d %d” are not valid. If these specifiers are not in the proper order, or if the string contains other % specifiers, an error is generated.
