Real world situation that use threads could lead to a race condition?

Could anyone give me an example of a real world situation where the use of threads could lead to a race condition? thx.

??? There never can be a RW situation that leads to a race condition as racing is always a bug.

What I think you mean is what causes a race condition? Well, that all depends on the software, but a race is when two threads/processes compete for the same resource

iim asking for a real world situation that uses threads that "might" (even though it's already implemented the safety) lead to a race condition

OK
A threaded application implements it's save and load settings functions in seperate threads. The user tells the application to save settings to a floppy.

Some applications (mine included) automatically reload settings after saving them. Depending on how this is implemented it may cause the threads to race as the "save" thread is saving to the floppy and the "load" thread is trying to read the same bit.

Crappy example, but there you go
