c++ - How to convert pointer value obtained via reference operator to string? -

-

i beginner in c++. working on project required trace memory address. unfortunately, tracing function has following prototype declaration:

void trc(uint8_t, uint8_t, uint8_t, uint64_t, uint64_t, uint64_t, uint64_t, uint64_t, uint64_t, const char*)

now options available me are:

  1. convert memory address (pointer value) uint64_t type. i've read somewhere not recommended, pointer value returned reference operator platform dependent , conversion of pointer integer may return wrong value.

  2. convert memory address string , pass via last parameter. in python easy had str() function. have similar in c++ too?

please let me know if inferring wrong in approach/understanding here.

you use streams convert if not need fast code.

    #include <sstream>     #include <iomanip>  ...     std::ostringstream os;     os << std::hex << static_cast<void*>(my_pointer);     trc(..., os.str().c_str());

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
