The problem I have with this thread (no pun intended) is that it is not
comparing like with like. As demonstrated by many of the replies,
Parallelism and Threads are not the same thing.
I would offer the following definitions:
- Parallelism is a (design) concept for expressing collateral actio

Nevertheless, that should work.
I've used it in multi-threaded apache modules.
Well it doesn't work or fpjson module is not thread safe in this case.
Hello.
Once again, fpc has nothing to do with that problem.

Ok, (grrr...), I will follow this notice.
PS: If I may, I find strange that Microsoft cannot make libraries
Thanks a lot! Seems to working fine now

I use this:

Hello,
What is the recomended way to deal with string constants in units which are
shared in cross-platforms projects?
For example, i started a project in Linux, where the source code files are
saved in UTF-8. If i use theses files in Windows, the constants aren't
automatically converted to the s

As far as the compiler is concerned what’s the difference between clearing an
array using a for-loop vs. FillChar? It seems like iterating the array would be
slower but what does FillChar do exactly and is it faster? The primary concern
here is that the memory originally allocated (using SetLeng
I’ve been using a design pattern in my code which I think is probably pretty
stupid so I’d like to make sure. Assume I have a type like TPoint below and I
want to set the value I’ll doing something like point := PointMake(x, y). How
does the compiler handle this? It probably has to allocate some
Hi all,
I'm looking for official reference for function/procedure parameter list
declaration in Pascal. I found this:
http://www.freepascal.org/docs-html/ref/refse91.html but I think it's not
really clear, especially for newbie. For example, when exactly we need to
use/put ; (semicolon) instead
23 matches
