ExIsResourceAcquiredSharedLite function

The ExIsResourceAcquiredSharedLite routine returns whether the current thread has access (either shared or exclusive) to a given resource.

Syntax

ULONG ExIsResourceAcquiredSharedLite(
  PERESOURCE Resource
);

Parameters

Resource

A pointer to the resource to be queried.

Return Value

ExIsResourceAcquiredSharedLite returns the number of times the caller has acquired the given resource for shared or exclusive access.
