_InterlockedDecrement

  • Article

This function performs an atomic addition of a decrement value to an addend variable. The function prevents more than one thread from using the same variable simultaneously.

InterlockedDecrement(
  PLONG Addend
);

Parameters

  • Addend
    [in] Value to be decremented.

Return Values

Result of binary arithmetic.

Remarks

The interlocked functions 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.

Requirements

OS Versions: Windows CE .NET 4.0 and later.
Header: Mipsintr.h.
