The only concurrency issues that seem to come up in CF are when we need to single thread any piece of code - that's what the locks do. But I haven't seen any code at all that allows us to start new threads in the same page. As I understand it, C++ is a multi-threaded language. CFAS is a multi-threaded application written in C++. CFML is a single-threaded language that needs to take into account multiple threads on occasion.
Please correct me if I'm wrong. - Matt Small -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Monday, March 18, 2002 4:10 PM To: CF-Talk Subject: Re: UDF question CF is merely an abstraction of a crap load of C++ code. I agree with you on the process that happens when you define a variable in CF. I don't see how that absolves the programmer of coming up with the best way of handling concurrency issues. Regardless, CF does provide you with many mechanisms of locking control. What really matters is picking the one that suits you, and to write code that is in line with the decision you've made. ----- Original Message ----- From: junkMail <[EMAIL PROTECTED]> Date: Monday, March 18, 2002 1:18 pm Subject: Re: UDF question > With respect to this issue, comparing CFML to C++ is apples to > oranges. > I can't expect a low-level language to automatically manage > concurrent access > to shared memory resources, because I have defined the resources > and I have > decided how they are to be accessed and shared.
