Function Documentation

TNCThreadIndex g_GetNCThreadIndex (  void   )

Get index of the current thread. All threads are indexed with incrementing numbers starting from 1. Thread is indexed only when this function is called and if it wasn't indexed yet. Definition at line 51 of file nc_utils.cpp. References CAtomicCounter::Add(), NCTlsGet, NCTlsSet, s_NCThreadIndexKey, and s_NextThreadIndex. Referenced by CNCServerStat_Getter::CreateTlsObject(), CNCMMSizePool_Getter::CreateTlsObject(), CNCMMChainsPool_Getter::CreateTlsObject(), CNCMMChunksPool_Getter::CreateTlsObject(), CNCMMStats_Getter::CreateTlsObject(), and CNCDBStat::CreateTlsObject().

void g_InitNCThreadIndexes (  void   )

Initialize system that will acquire thread indexes for each thread. This function must be called before g_GetNCThreadIndex() is used. Definition at line 44 of file nc_utils.cpp. References NCTlsCreate, s_NCThreadIndexKey, s_NextThreadIndex, and CAtomicCounter::Set().
