MapForeachValuePtrForKey

Description

Iterate over all values stored for a specific key with pointers.

Parameters

Success

The loop body runs once for each value stored under lookup_key, with value_ptr bound to the in-slot value address. Use this form when the body mutates the stored value in place. The body is skipped when m is empty or when the key is not present.

Failure

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