[Wxlua-users] Abort a running wxLua script (RunFile)

[<hel...@gm...>]

Hello,
one more question on wxLua in a multi-threading application (several threads should host their own Lua instance).
I create a wxLuaState object for every thread and use RunFile to execute the script.
After calling "RunFile" I loose control and have to wait until the script ends.
Is there a possibility to abort the script execution by the hosting application/thread? Maybe by sending an event or something to wxLua?

@John Labenski: Thank you for your response to my question "Multiple Lua instances in multi-threading app", it made sense, indeed :-)

Yours,
Helmut

Try using wxLuaState::SetDebugHookBreak or at least see the code in
modules/wxlua/wxlstate.cpp which sets the debug hook function to
wxLua_lua_debugHookFunction which you can use as a template of how to
jump into a lua program while it's running. Just replace the code in
wxLuaState::SetDebugHookBreak to have the lua_State hook into your own
debug function.

I am not too familiar with coroutines, but these might also be helpful.
