FltReleaseResource function (fltkernel.h)

  • Article

The FltReleaseResource routine releases a specified resource owned by the current thread.

Syntax

VOID FLTAPI FltReleaseResource(
  [in/out] PERESOURCE Resource
);

Parameters

[in/out] Resource

Pointer to the opaque ERESOURCE structure for the resource to be released.

Return value

None.

Remarks

FltReleaseResource releases a resource that was previously acquired by calling FltAcquireResourceExclusive or FltAcquireResourceShared.

FltReleaseResource is a wrapper for ExReleaseResourceLite that reenables normal kernel APC delivery.

Because FltReleaseResource reenables normal kernel APC delivery, it is not necessary to call KeEnterCriticalRegion or FsRtlEnterFileSystem after calling FltReleaseResource.

To acquire a resource for exclusive access, call FltAcquireResourceExclusive.

To acquire a resource for shared access, call FltAcquireResourceShared.

To delete a resource from the system's resource list, call ExDeleteResourceLite.

To initialize a resource for reuse, call ExReinitializeResourceLite.

For more information about ERESOURCE structures, see Introduction to ERESOURCE Routines.
