Get working on Windows #8

Closed richfitz closed 7 years ago

richfitz commented 7 years ago

I don't think that it's going to be easy to get an "interrupt" working on windows. This code:

#include <Windows.h>
#include <R.h>
void test() {
  for (int i = 0; i < 10; ++i) {
    Rprintf("hello %d\n", i);
    if (i == 4) {
      GenerateConsoleCtrlEvent(CTRL_C_EVENT, 0);
    }
    R_CheckUserInterrupt();
  }
}

Will correctly stop the loop after the 5th iteration but will then terminate the R process (within Rterm) and leave the console in an unusable state. Run from within Rgui, nothing happens.

So that leaves us with the ability to kill workers only.

Working on windows now. The interrupt does not work, but we should be able to send termination anyway
