My original reply was too long for Cocoa Dev; then I lost it.
So this is another (small draft)...
It appears I'll be working with blocks, keeping the data/functioning local
to the stack copying data out to the GUI:
typedef sat_t (^MyBlock)();
// C - function:
int addFoot(int k) {
Environment: iOS SDK 4.2+
Xcode 3.2.5
Desired design:
1) Multiple NSThreads (via NSOperation?) running NSObjects in parallel:
processing the same C-functions (with different data) in real time till
conclusion (or cancelled).
2) These C-functions are located in a common *.c file (or two);
