### LogCustomPropertyMask

This property specifies the bitmask that can be used against the metabase property, specified by LogCustomPropertyID, to determine whether the particular logging field is currently enabled or disabled.

When a logging module is asked to log custom information fields, the logging module will access the property specified by LogCustomPropertyID, and check the individual flag bits, specified by LogCustomPropertyMask, to determine if that particular field is currently enabled or disabled.

For more information about custom logging fields, see Setting Metabase Properties for Logging in the Platform SDK.
