int get_eval_number()
|
|
Return the current evaluation number. It's incremented for each top-level call. [...]
|
|
|
|
The intended purpose of this function is to find out if something has already been done for the current command, heart_beat, call_out or whatever. Control flow in mudlibs is often complicated and adding the necessary infrastructure to a mudlib to answer this question is error-prone and tedious. In the driver it's just a few lines of code.

+SYNOPSIS

|
+ int get_eval_number()
|
|
+
|
|
+DESCRIPTION
|
|
+ Return the current evaluation number. It's incremented for each
|
|
+ top-level call. These are: commands, calls to heart_beat, reset,
|
|
+ or clean_up, and calls generated by call_out or input_to, master
|
|
+ applies triggered by external events, send_erq callbacks and the
|
|
+ calls to logon on player login.
|
|
+
|
|
+ The counter is a 32 bits counter so it can overflow occasionally.
