[C++] _beginthreadex e WaitForSingleObject

[gianvituzzi]

Salve,

lanciando un thread con questo codice:

unsigned int prodRet;
_beginthreadex(0,0,startRecorder,NULL,0,&prodRet);

come faccio per rintracciarne l'handle per poi fare:

WaitForSingleObject(HANDLE, INFINITE)

???

grazie

[Stoicenko]

devi per forza usare la _beginthreadex?

[gianvituzzi]

assolutamente si
