it's more this way:
smsc modules have IO threads, those get registered via log_to_thread() to a specific log-file and inside the smsc module code you don't have to change anything in the logging functions, which was my most concern about it.
which was what made it so easy to roll into our smpp server.
The problem is that the "thread_id" is used as an index into the logfiles array. The thread id is essentially incremented for each thread created, so under certain circumstances this can easily be higher than 1024. Either through server apps, or lots of use of the stop/start smsc admin functions etc.
The thread id the logging functions use come from the gwlib thread functions that maintain a thread table. Each new thread increments the thread id, and the entry into the table is calculated by "threadnumber % THREADTABLE_SIZE", The new thread code checks for free slots. This is way to slow for logging purposes.
But surely then we could in log_thread_to use the same idea
thread_to[thread_id % THREADTABLE_SIZE] = idx
Given that the thread creation code has allready checked that the slot "threadnumber % THREADTABLE_SIZE" is free in the thread table and the threadnumber is the thread_id.
