]Interlocked::CompareExchange(int32_t&, int32_t, int32_t, bool&) method
Compare-exchanges value on variable: checks if variable is equal to specific value and stores the new value only if stored value matches expected.
static int32_t System::Threading::Interlocked::CompareExchange(int32_t &location1, int32_t value, int32_t comparand, bool &succeeded)
| Parameter | Type | Description |
|---|---|---|
| location1 | int32_t& | Variable reference to change. |
| value | int32_t | Value to store. |
| comparand | int32_t | Value to compare variable’s value to before exchanging. |
| succeeded | bool& | Reference to variable which is set to true if exchange took place and to false otherwise. |
ReturnValue
Value of variable on operation start regardless whether it was changed or not.
