warning C28137: The variable argument should instead be a (literal) constant

This warning is reported when a function call is missing a required (literal) constant. Consult the documentation for the function.

For example, the ExAcquireResourceExclusiveLite routine requires a value of TRUE or FALSE for the Wait parameter. The following example code generates this warning:

ExAcquireResourceExclusiveLite(Resource, Wait);  

The following code example avoids this warning:

ExAcquireResourceExclusiveLite(Resource, TRUE);
