C++ (Cpp) initAllocator Examples

Example #1

File: scudo_allocator.cpp Project: CSI-LLVM/compiler-rt

static void initInternal() {
  SanitizerToolName = "Scudo";
  CHECK(!ScudoInitIsRunning && "Scudo init calls itself!");
  ScudoInitIsRunning = true;

  initFlags();

  AllocatorOptions Options;
  Options.setFrom(getFlags(), common_flags());
  initAllocator(Options);

  ScudoInitIsRunning = false;
}
