How to set name to a Win32 Thread?

Question

How do I set a name to a Win32 thread. I did'nt find any Win32 API to achieve the same. Basically I want to add the Thread Name in the Log file. Is TLS (Thread Local Storage) the only way to do it?

Answer 1

Does this help ? How to: Set a Thread Name in Native Code

In managed code, it is as easy as setting the Name property of the corresponding Thread object.

// Usage: SetThreadName (-1, "MainThread");

#include <windows.h>
const DWORD MS_VC_EXCEPTION=0x406D1388;

#pragma pack(push,8)
typedef struct tagTHREADNAME_INFO
{
   DWORD dwType; // Must be 0x1000.
   LPCSTR szName; // Pointer to name (in user addr space).
   DWORD dwThreadID; // Thread ID (-1=caller thread).
  DWORD dwFlags; // Reserved for future use, must be zero.
} THREADNAME_INFO;
#pragma pack(pop)

void SetThreadName( DWORD dwThreadID, char* threadName)
{
   THREADNAME_INFO info;
   info.dwType = 0x1000;
   info.szName = threadName;
   info.dwThreadID = dwThreadID;
   info.dwFlags = 0;

   __try
   {
      RaiseException( MS_VC_EXCEPTION, 0, sizeof(info)/sizeof(ULONG_PTR),       (ULONG_PTR*)&info );
  }
  __except(EXCEPTION_EXECUTE_HANDLER)
  {
  }
}
