Syntax
HRESULT GetSignalQuality(
[out] ULONG *puStrengthValue,
[out] ULONG *puStrengthMax
);
Parameters
[out] puStrengthValue
The current signal strength. This parameter takes a ULONG value between 0 and puStrengthMax.
[out] 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.
| Return code | Description |
|---|---|
|
The method completed successfully. |
|
The method failed. |

One of the parameters is invalid. |
|
The method could not allocate the memory required to perform this operation. |
|
A pointer passed as a parameter is not valid. |
Remarks
Signal strength, in this context, is measured on a linear scale. When puStrengthMax is set to the default value of 100, puStrengthValue represents the percentage of the maximum signal strength currently used for transmission.
