  ULONG *puStrengthMax
);

Parameters

puStrengthValue

The current signal strength. This parameter takes a ULONG value between 0 and puStrengthMax.

puStrengthMax

The maximum signal strength value. This parameter takes a ULONG value between 0 and 100. By default, puStrengthMax is set to 100.

Return value

Possible return values include, but are not limited to, the following.
