During my work adventures, I have the ‘fortune‘ of working with Windows threads. One thing that’s nice to have is a name for each thread so you can actually tell them apart. Turns out, there is no easy call to set a thread name.
However, there is an officially approved way to set a thread name:
//
// Usage: SetThreadName (-1, "MainThread");
//
typedef struct tagTHREADNAME_INFO
{
DWORD dwType; // must be 0×1000
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;
void SetThreadName( DWORD dwThreadID, LPCSTR szThreadName)
{
THREADNAME_INFO info;
info.dwType = 0×1000;
info.szName = szThreadName;
info.dwThreadID = dwThreadID;
info.dwFlags = 0;
__try
{
RaiseException( 0×406D1388,
0, sizeof(info)/sizeof(DWORD),
(DWORD*)&info );
}
except(EXCEPTION_CONTINUE_EXECUTION)
{
}
}
Who is the genius responsible for that idea???
