[fpc-pascal] TThread.Queue vs TThread.Synchronize

[Philippe Lévi]

sorry ... I still not understand the "idea".


if code in thread access a local variable (in stack) of the function where thread is issued ... it may access "something" which does not exist any more. correct?

    you mean it will be possible to use a pointer to local function in a
    call?

    or I misunderstand ...

    Please read the following part of my message again:

Oops, sorry. Just confusion on translation.

you mean it will be possible to use a pointer to local function in a call? ²

(some switch to enable this feature?)

See the mail I just sent to the list. In short: yes, but not exactly as I presented in my example with TThread.Queue().

I saw. It is very nice. Thank you! =)
