示例1: HeapSnapshotMethodCallback
void Profiler::HeapSnapshotMethodCallback(const v8::FunctionCallbackInfo<v8::Value>& args)
{
struct timespec nowt;
clock_gettime(CLOCK_MONOTONIC, &nowt);
uint64_t now = (int64_t) nowt.tv_sec*1000000000LL + nowt.tv_nsec;
unsigned long sec = static_cast<unsigned long>(now / 1000000);
unsigned long usec = static_cast<unsigned long>(now % 1000000);
char filename[256];
snprintf(filename, sizeof(filename), "/sdcard/%s-heapdump-%lu.%lu.heapsnapshot", s_appName.c_str(), sec, usec);
FILE* fp = fopen(filename, "w");
if (fp == nullptr)
{
return;
}
Isolate* isolate = Isolate::GetCurrent();
const HeapSnapshot* snap = isolate->GetHeapProfiler()->TakeHeapSnapshot();
FileOutputStream stream(fp);
snap->Serialize(&stream, HeapSnapshot::kJSON);
fclose(fp);
