This function increments the value of the specified 32-bit variable and checks the resulting value. InterlockedIncrement prevents more than one thread from using the InterlockedDecrement function or InterlockedIncrement function to access the same variable simultaneously.


LONG InterlockedIncrement(
  LPLONG lpAddend
);

lpAddend

[in] Pointer to the LONG variable to increment.

Incremented value.

The functions InterlockedIncrement, InterlockedCompareExchange, InterlockedDecrement, InterlockedExchange, and InterlockedExchangeAdd provide a simple mechanism for synchronizing access to a variable that is shared by multiple threads. The threads of different processes can use this mechanism if the variable is in shared memory.

The variable pointed to by the lpAddend parameter must be aligned on a 32-bit boundary.
