_InterlockedExchangeAdd (Windows Embedded CE 6.0)
1/5/2010
This function performs an atomic addition of an increment value to an addend variable. The function prevents more than one thread from using the same variable simultaneously.
Syntax
InterlockedExchangeAdd(
PLONG Addend,
LONG Increment
);
Parameters
- Addend
[in, out] Value to be incremented.
- Increment
[in] Value used to increment Addend.
Return Values
The initial value of the variable pointed to by Addend.
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.
