UINT __stdcall ThreadProc_Calc(VOID * pParam)
pParam : (IN/OUT) THREAD_PARAMS_CALC struct pointer special for this thread
Return Value:
returns 0
Notes:
- requests jobs from the queue and calculates hashes until the queue is empty
- spawns up to three additional threads, one for each hash value
- performs asynchronous I/O with two buffers -> one buffer is filled while the hash-threads
work on the other buffer
- if an error occured, GetLastError() is saved in the current pFileinfo->dwError
- what has be calculated is determined by bDoCalculate[HASH_TYPE_CRC32]/bDoCalculate[HASH_TYPE_MD5]/bDoCalculate[HASH_TYPE_ED2K] of the
current job
