UDT source code analysis (2) start and end

UDT's startup routine

Startup routine sequence:void UDT::startup() -> void CUDT::startup() -> void CUDTUnited::startup() -> void* CUDTUnited::garbageCollect(void* p) -> void CUDTUnited::checkBrokenSockets() -> void CUDTUnited::removeSocket(const UDTSOCKET u) -> void CUDT::close() -> void CUDT::flush()

• For a complete UDT SOCKET cleanup six-part:
  • Set the state of CUDT* to BROKEN
  • Call close() in CUDT
  • Update the closing time of UDT SOCKET
  • Set UDT SOCKET to Closed
  • Add the current UDT SOCKET to the Closed Array and process it in the GC thread
  • Remove from global MAP
