C++ (Cpp) TEST_STRT Examples

Example #1

File: crowd_basic_mkrun_desch.c Project: baileyparker/os-assignment7-crowdtested

/* Tests that a thread returns from desch() only after being mkrun()'d */
int
main(void)
{
  int i, child;
  char *stack;

  TEST_STRT(ITERATIONS);

  for(i = 0; i < ITERATIONS; i++) {
    stack = malloc(STACKSZ);
    TEST_EXIT_IF(stack == 0, "malloc failed");
    stack += STACKSZ; // Must give pointer to top of the stack

    child = tspawn(stack, thread_func, (void *) i);

    TEST_EXIT_IF(child < 0, "tspawn failed");

    sleep(64); // #YOLOMAGICNUMBER
    has_mkran[i] = 1; // inform child they have actually been awoken
    TEST_EXIT_IF(mkrun(child) < 0, "mkrun failed");

    // #YOLOLEAK because we have no uthr_join
    // and we can't free until texit()
    // free(stack);
  }

  texit();
