InterlockedExchange (Windows CE 5.0)

Windows CE 5.0
Send Feedback

This function atomically exchanges a pair of 32-bit values.

LONG InterlockedExchange( 
  LPLONG Target, 
  LONG Value 
); 

Parameters

Target
[in] Pointer to the LONG value to exchange. The function sets this LONG value to Value, and returns its prior value.
Value
[in] Specifies a new value for the LONG value pointed to by Target.

Return Values

The prior value of the LONG value pointed to by Target indicates success.

Remarks

The functions InterlockedExchange, InterlockedCompareExchange, InterlockedDecrement, InterlockedExchangeAdd, and InterlockedIncrement 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 Target parameter must be aligned on a 32-bit boundary; otherwise, this function will fail on systems other than x86 systems.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Winbase.h.
Link Library: Coredll.lib.
