On 19 Apr, Rodos scribbled:
-> I am writing an application in C on Linux.
->
-> Here is my problem. There are three things the program does, writes out
-> to a serial port. Reads and writes to the parallel port, and
-> communicates with a database. The thing is that the serial and database
-> stuff might block or timeout for periods of time (say 1 to 10 seconds).
-> However I need to constantly poll the serial port for data.
->
-> Therefore I am not sure as to the best way to architect my program.
-> First thing that comes to mind is threads, but that sounds to hard for
-> me (not that I have looked at it yet). Other things are forking 3 tasks
-> and getting them to comminute with each other (how I don't know yet).
->
-> So what do you gals and guys recommend, is there a common way of doing
-> such things? Is there a good C/Unix book that I should get ASAP. I have
-> flipped through my Kernighan "The Unix Programming Environment" and it
-> has a bit on forking but not a lot.
select(); is your friend. it sure as hell is mine :)
man 2 select
-> Thanks for the advise.

-> Rodos

-> P.S. I have ODBC working straight to an NT machine from my C program.
-> Way cool. I will be able to turf out more NT machines on this projects
-> and future ones when it is mandated that MS SQL is the database
-> platform. I am planning on writing a very small howto type thing on it.
