MapSwap

Description

Swap two maps of the same type.

Parameters

Success

Returns to the caller. Storage, callbacks, policy, and allocator of lhs and rhs have been exchanged byte-for-byte; neither map’s contents are touched.

Failure

Function cannot fail. Validation of either argument is a caller bug and aborts via LOG_FATAL.

Usage example (Cross-references)

        result = result && (MapUniqueKeyCount(&first) == 2);
    
        MapSwap(&first, &second);
    
        result = result && MapContainsPair(&first, 9, 90);
