making a threadsafe localtime

[Responding here in case other folks see this and don't read your later responses] Sure, synchronization objects take time to execute, but having reliable, robust code that may be slower is preferable to faster code that is susceptible to corruption.

Hi i recently had the same problem and came up with this solution ..

// Global monitor object for the localtime function
CCriticalSection oLockLocaltime;

void MPSLocaltime(const time_t& ttTime,struct tm* ptrTM)
{
if(! ptrTM)
return;

CSingleLock oLock(&oLockLocaltime);

oLock.Lock();

struct tm* ptrTmLoc;
ptrTmLoc = localtime(&ttTime);

memcpy(ptrTm,ptrTmLoc,sizeof(struct tm));

oLock.Unlock();

}

This should do the trick ..
I didn't used CCriticalSection but some lock object for linux i wrote. I is based on the pthread lib but it basically works exactly like the CCriticalSeection/CSingle lock combo under Win32. I know because when i compile the code inside windows i simply change the base class to CCriticalSection/CSingleLock.

Greetings ..
