Passing parameters when launching threads.

[Matt Grace]

Shesh, 'been a while since I've posted, PB's running wonderfully, to all you folks at PB, keep it up.

Now to my question - I'm beginning to make use of threads in my apps, and I'm extremely pleased with the efficiency and various benefits I'm discovering. I currently have the need to pass more than one parameter to a thread, I actually need to pass two string parameters, but powerbasic only allows 1 long parameter per new thread. My two questions are as follows:

1 - What is the most efficient way to pass various parameters to a new thread, globals?, udt?, ptr to a udt (is that possible?), or ptr to a multi-dimensional string array that contains to the two parameters i need, or is it something else?

2 - Will this be changed in future versions of PowerBasic? - if not, may I add it to the suggestion list. Thanks.

Thanks in advance.

I think a pointer to a UDT is the best way to go, use string pointers in the UDT if you need variable length strings

TYPE PassType
   String1 As String Ptr
   String2 As String Ptr
END TYPE

I shouldn't think it would change, as the WinApi thread functions only require 1 parameter (Long, See 'CreateThread').
