Assembly: mscorlib (in mscorlib.dll)
public: static IntPtr CompareExchange( IntPtr% location1, IntPtr value, IntPtr comparand )
- Type: System::IntPtr%
The destination IntPtr, whose value is compared with the value of comparand and possibly replaced by value.
- Type: System::IntPtr
The IntPtr that replaces the destination value if the comparison results in equality.
Return ValueType: System::IntPtr
The original value in location1.
If comparand and the value in location1 are equal, then value is stored in location1. Otherwise, no operation is performed. The compare and exchange operations are performed as an atomic operation. The return value of this method is the original value in location1, whether or not the exchange takes place.
