Re: Using defines for protocol characters

Hi, I wondered if any consideration was given to using an enum instead
of all the #defines.

I guess, your patch would not be much different; you can still have
all the nice names and assign the appropriate values to the enum
values same as now, but using an enum you might also gain
type-checking in the code and also get warnings for the "switch"
statements if there are any cases accidentally omitted.

For example, see typedef enum LogicalRepMsgType [1].
