MapForeachValue

Description

Iterate over all stored values by value.

Parameters

Success

The loop body runs once per occupied slot with value_var bound to a copy of the stored value. The body is skipped when m is empty. Mutating the local does not write back into the map.

Failure

The macro itself does not fail. LOG_FATAL via ValidateMap(m) when m is uninitialised or corrupted.
