/* Definitions for the SMTP commands
|
|
|
|
SMTP commands can be added, and deleted by editing the header file
|
|
smtpdef.h. This header file should never be touched. Smtpdef.h
|
|
has a table describing every command the smtp serversupports.
|
|
For instance, a few entries in this file contains :
|
|
|
|
SmtpDef(NEWSMTPCOMMAND1)
|
|
SmtpDef(NEWSMTPCOMMAND2)
|
|
SmtpDef(NEWSMTPCOMMAND3)
|
|
SmtpDef(NEWSMTPCOMMAND4)
|
|
SmtpDef(NEWSMTPCOMMANDETC)
|
|
|
|
|
|
Other source files include atmdef.h, *AFTER* defining the AtmDef macro to extract only
|
|
the value needed. For instance, below we need an enumeration of all the counters (ATMCOUNTERS).
|
|
Therefore, before including atmdef.h, we make a macro to extract the first element of
|
|
the array :#define SmtpDef(a) a,. Notice the comma at the end of the #define. It is
|
|
not a mistake. It needs to be there to separate each element.
|
|
|
|
To define an array of SDef, we do the following :
|
|
enum smtpstate =
|
|
{
|
|
#undef SmtpDef
|
|
#define SmtpDef(a) {a},
|
|
#include "smtpdef.h"
|
|
LastCounter
|
|
};
|
|
|
|
Notice that we first have to undefine the previous instance of SmtpDef, then make
|
|
a new defination of the macro, which extracts all the element. Again, notice the
|
|
comma. It needs to be there to separate each element. Also, notice how the array
|
|
is terminated.
|
|
|
|
The beauty of doing it this way is because, to add or delete a command, only one file
|
|
has to change. Not two or three.
|
|
|
|
I hope all of this makes sense.
